Cook the rice: Rinse 1 cup of rice under cold water, then cook according to package directions. Fluff and set aside.
For extra flavor, add a pinch of salt and a squeeze of lime to the cooked rice.
Prep the chicken: Pat chicken dry. Cut into bite-sized pieces or thin strips for quicker cooking. In a bowl, toss chicken with olive oil, taco seasoning, cumin, smoked paprika, garlic powder, onion powder, salt, pepper, and lime juice.
Sear the chicken: Heat a large skillet over medium-high heat with a light drizzle of oil.
Add chicken in a single layer. Cook 6–8 minutes, stirring once or twice, until browned and cooked through. Remove to a plate to rest.
Cook the veggies: In the same skillet, add sliced bell peppers and red onion with a small splash of oil if needed.
Season with a pinch of salt and pepper. Cook 4–5 minutes until slightly softened but still crisp.
Warm the beans and corn: Add black beans and corn to the skillet for 1–2 minutes to heat through. You can also keep them cold if you prefer a contrast in temperature.
Build the bowls: Divide rice among 4 meal prep containers.
Top with chicken, peppers and onions, black beans, and corn. Spoon over a bit of salsa. Sprinkle with cilantro.
Finish and store: Let everything cool slightly.
Add a lime wedge to each container. Keep Greek yogurt and avocado separate until serving so they stay fresh.
