Cook the rice: Rinse 2 cups of rice under cold water until the water runs clear.
Cook according to package directions. For extra flavor, use low-sodium chicken broth instead of water. Fluff with a fork and set aside.
Preheat and prep: Preheat your oven to 425°F (220°C).
Line a large sheet pan with parchment paper for easy cleanup. Chop the bell peppers and red onion into bite-size pieces, slice the carrot thinly, and cut broccoli into small florets.
Mix the seasoning: In a small bowl, stir together smoked paprika, garlic powder, onion powder, dried oregano, cumin, chili powder, salt, and pepper.
Season the chicken: Pat the chicken dry, then slice into 1-inch pieces or thin cutlets for faster, even cooking. Toss with half of the seasoning mix and 1 tablespoon olive oil.
Season the veggies: On the sheet pan, toss the chopped veggies with the remaining seasoning and 1 tablespoon olive oil.
Spread them into an even layer.
Roast: Add the chicken to the sheet pan, keeping it in a single layer. Roast for 16–20 minutes, flipping the chicken halfway. The chicken should reach an internal temperature of 165°F (74°C) and the veggies should be tender with a little char.
Make the quick sauce: In a small bowl, whisk lemon juice, soy sauce, honey, and minced garlic.
Taste and adjust—add more lemon for brightness or honey for sweetness.
Optional chickpeas: If using chickpeas, toss them with a pinch of salt and a splash of olive oil. Add to the sheet pan for the last 8–10 minutes to warm and crisp slightly.
Assemble bowls: Divide the cooked rice among 5 meal prep containers. Top with roasted chicken and vegetables.
Drizzle each portion with the sauce. Sprinkle with chopped parsley or cilantro if you like.
Cool before sealing: Let the bowls cool for 15–20 minutes at room temperature before closing the lids to prevent condensation from making everything soggy.
