Ingredients
  

  • 1.5 to 2 pounds boneless, skinless chicken breasts (or thighs)
  • 3 bell peppers (mixed colors), sliced into strips
  • 1 large red onion, sliced into wedges
  • 2 tablespoons olive oil, divided
  • 1 lime (zest and juice)
  • Fresh cilantro (optional, for garnish)
  • 4 cups cooked brown rice or quinoa (about 1 cup dry before cooking)
  • 1 can (15 oz) black beans, rinsed and drained
  • 1 avocado (optional, for day-of topping)
  • Greek yogurt or light sour cream (optional)
  • 2 teaspoons chili powder
  • 1 teaspoon ground cumin
  • 1 teaspoon smoked paprika
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1/2 teaspoon oregano
  • 1/2 teaspoon kosher salt (plus more to taste)
  • 1/4 teaspoon black pepper
  • 1/8 to 1/4 teaspoon cayenne (optional, for heat)

Method
 

  1. Cook Your Base: Make brown rice or quinoa according to package directions. Fluff and let it cool slightly so it doesn’t steam up your containers. For extra flavor, cook with low-sodium chicken broth and a squeeze of lime.
  2. Mix the Spice Blend: In a small bowl, combine chili powder, cumin, smoked paprika, garlic powder, onion powder, oregano, salt, pepper, and cayenne if using. This rub is the heart of the dish.
  3. Prep the Chicken: Pat the chicken dry. Slice breasts into even strips about 1/2 to 3/4 inch thick for quick, even cooking. Toss with 1 tablespoon olive oil, half the spice blend, and half the lime zest.
  4. Prep the Veggies: Slice bell peppers and onion. Toss with the remaining 1 tablespoon olive oil, the rest of the spice blend, and a pinch of salt.
  5. Choose Your Cooking Method: For easy cleanup, use a sheet pan. For deeper char and faster cooking, use a large cast-iron skillet.
  6. Sheet Pan Method: Heat oven to 425°F (220°C). Spread veggies on one side of a large sheet pan and chicken on the other. Roast 15–20 minutes, flipping halfway, until chicken reaches 165°F (74°C) and edges get a little caramelized.
  7. Skillet Method: Heat a large skillet over medium-high. Sear chicken in batches 3–4 minutes per side until cooked through. Remove, then cook veggies 5–7 minutes until tender-crisp with some char. Return chicken to the pan and toss with lime juice.
  8. Finish With Lime: While hot, squeeze in the lime juice and sprinkle the remaining zest. This brightens everything and keeps flavors lively through the week.
  9. Assemble the Bowls: Divide rice or quinoa into 4–5 containers. Add black beans, then top with chicken and veggies. If using cilantro, sprinkle it over now.
  10. Cool Before Sealing: Let containers sit uncovered 10–15 minutes so condensation doesn’t make things soggy. Then seal and refrigerate.
  11. Day-Of Toppings: Add avocado, a spoon of Greek yogurt, or a little salsa right before you eat for fresh contrast and creaminess.
