# how to meal prep for the week
A week of healthy lunches can cost less than $20 if you batch-cook three core ingredients on Sunday and mix them into five different meals. The plan works like this: roast chicken thighs, cook a batch of whole-wheat couscous, hard-boil four eggs, whisk two simple vinaigrettes, and prep kale. Each lunch assembles in minutes from those components.
This guide is for anyone who wants to eat well during the workweek without spending $12 per meal on takeout. No advanced cooking skills needed. If you can set a timer and use a baking sheet, you can handle this. Sunday ends with five grab-and-go lunches in the fridge and a stock of components you can remix for dinner too. Total hands-on time runs about 45 minutes, plus roughly 30 minutes of oven time that doesn't need your attention.
- A baking sheet lined with foil or parchment paper - A medium pot with a lid for the couscous - A small saucepan for boiling eggs - Two jars with lids for the dressings - A large bowl for washing and chopping kale - Four to five lunch containers with tight lids
Check your pantry before shopping. You likely already own olive oil, vinegar, mustard, and salt. That keeps the grocery bill closer to the $20 target. If your store sells couscous in bulk, buy just the 2/3 cup you need instead of a whole box. The same logic applies to chicken: two thighs from the meat counter beat a family pack you'll struggle to use.
Set the oven to 425°F and arrange two boneless, skinless chicken thighs on your foil-lined baking sheet. Season with salt and pepper, then roast for 25-30 minutes until the internal temperature hits 165°F. The foil makes cleanup a non-event: lift it out and toss it.
Chicken thighs are the budget-friendly protein here because they stay moist even if you slightly overcook them. Lean chicken breasts turn dry and stringy under the same treatment. While the chicken roasts, you can knock out the next two steps.
The chicken is done when a thermometer reads 165°F in the thickest part. If you don't have a thermometer, pierce the thickest spot. Clear juices running out mean it's ready.
Bring 1 cup of water to a boil in a medium pot, add a pinch of salt, then stir in 2/3 cup of whole-wheat couscous. Cover, remove from heat, and let it stand for 5 minutes. Fluff with a fork before measuring it out for the lunches.
Couscous is the fastest grain you can cook. There's no simmering or stirring, just a soak. The whole-wheat version adds more fiber than the refined kind, which helps the lunches keep you full until dinner.
The couscous is ready when it's tender and each grain separates easily with a fork. If it clumps, it needed another minute of standing time. Fluffing with the fork fixes most of it.
Place four eggs in a small saucepan and cover with cold water by about an inch. Bring to a boil, then turn off the heat, cover, and let them sit for 12 minutes. Transfer to a bowl of ice water to stop the cooking.
The ice bath stops the yolks from turning gray-green and makes the shells peel cleanly. Skip this step and you'll fight the shells.
The eggs are done when they're cool enough to handle and the shells crack away easily. A perfectly cooked yolk is solid yellow with no dark ring around it.
Blend a handful of fresh basil, 2 tablespoons of olive oil, 1 tablespoon of vinegar, and a pinch of salt in a small food processor or by shaking vigorously in a jar. Taste and adjust the salt.
This bright green dressing flavors two of the five lunches and works as a quick salad dressing for dinners later in the week. Not all of it goes into the lunches, and that's the point.
The vinaigrette is ready when it's emulsified into a single, slightly thick liquid that coats the back of a spoon. Store it in a sealed jar in the fridge.
Combine 2 tablespoons of honey, 1 tablespoon of Dijon mustard, 2 tablespoons of olive oil, and 1 tablespoon of vinegar in a jar. Shake until smooth and creamy.
This dressing also works as a dipping sauce for raw vegetables or crispy chicken strips, so the extra jar earns its fridge space. If it separates in the fridge, that's normal. A quick shake brings it back.
The dressing is ready when it's smooth and pale yellow with no visible oil streaks. If it solidifies when cold, set the jar in a bowl of warm water for a few minutes before shaking again.
Strip the leaves from the stems, wash thoroughly, and chop into bite-sized pieces. You need about 3 cups for the lunches. Massage the chopped kale with a teaspoon of olive oil. This breaks down the tough fibers and makes it tender enough to eat raw.
Raw kale straight from the bunch is chewy and bitter, which is why so many people skip it. A quick massage with oil transforms the texture entirely.
The kale is ready when the leaves turn darker green and feel silky rather than stiff. A handful squeezed in your palm should hold its shape briefly before springing back.
Portion the components into five containers: each gets a base of couscous, a layer of chopped kale, one sliced chicken thigh, and half a hard-boiled egg. Add celery and carrot sticks to two of them, then drizzle the dressings. Use basil vinaigrette on three and honey-mustard on two.
Monday through Friday breaks down like this: the chicken grain bowl with celery and honey-mustard dressing starts the week, followed by the kale and chickpea salad with basil vinaigrette, then a repeat of the grain bowl with the remaining dressing.
Each container is a complete meal when it has a protein, a grain, a vegetable, and a dressing. The dressings keep the components moist without making the kale soggy. Store them separately and add just before eating if you prefer maximum crunch.
The lunches are ready when every container is sealed and labeled. The system proves itself on Wednesday when lunch takes 30 seconds to grab from the fridge.
**The chicken is dry.** You either overcooked it or used breasts instead of thighs. Fix it next week by pulling the chicken at 160°F and letting carryover cooking finish the job.
**The couscous is mushy.** You added too much water or let it sit too long. Use a 1:1 ratio of water to couscous and set a timer for the 5-minute stand.
**The eggs won't peel.** The eggs were too fresh or skipped the ice bath. Older eggs peel more easily. Buy them a week ahead if you can.
**The kale is still tough.** You didn't massage it long enough. Give it a full two minutes of squeezing and the texture changes noticeably.
**The dressings separated in the fridge.** That's normal. Olive oil solidifies when cold. Set the jar in warm water for five minutes, then shake hard.
The full process runs about 75 minutes from start to finish, but only 45 of those are hands-on. The chicken roasts unattended for 30 minutes, the couscous soaks for 5, and the eggs sit for 12. Use that downtime to knock out the dressings and kale.
- Two chicken thighs roasted to 165°F and sliced - 2/3 cup whole-wheat couscous cooked and fluffed - Four eggs hard-boiled and peeled - Two vinaigrettes made and stored in sealed jars - 3 cups of kale washed, chopped, and massaged - Five containers assembled with protein, grain, vegetable, and dressing
**Can I swap the chicken for something cheaper?** Yes. Canned chickpeas or lentils drop the protein cost to about $1 per lunch. Keep the couscous and kale the same, and the dressings will carry the flavor.
**How long do the lunches stay fresh?** Four days in the fridge is safe for the chicken-based containers. The kale and couscous hold up fine, but eat the egg-containing lunches by Wednesday for best quality.
**Can I freeze these lunches?** The couscous and chicken freeze well for up to three months. The kale and eggs don't. They turn watery and rubbery. Freeze the grains and protein, then prep fresh greens on Sunday.
**What if I don't like kale?** Spinach works as a direct swap and needs no massaging. It wilts faster, so add the dressing right before eating to keep it crisp.
**Do I need all five lunches to be different?** No. The two dressings create variety from the same base components. If you're happy eating the same thing daily, use one dressing for all five and skip the second jar.
**Is $20 realistic for a full week?** The cost per recipe lands around $1.79 when you buy ingredients in the right quantities. The trick is buying only what you need: bulk-bin couscous, two thighs from the meat counter, and pantry staples you already own.
You now have five lunches ready for the workweek and a fridge stocked with components you can remix for quick dinners. The dressings alone are worth keeping in rotation. They turn any grain-and-vegetable combo into a meal. Start with this menu once, then swap in whatever vegetables are on sale next week and watch the cost drop even further. Try this Sunday and see what your actual grocery receipt says. You might be surprised how far the $20 goes.
