Prep the base: Cook your cauliflower rice or grain of choice. Keep it plain or squeeze in some lime and a pinch of salt for brightness.
Season the chicken: Pat chicken dry.
Toss with taco seasoning, garlic powder, onion powder, salt, and pepper until evenly coated.
Sauté the veggies: Heat half the oil in a large skillet over medium-high heat. Cook bell pepper and red onion with a pinch of salt for 3–4 minutes until slightly tender. Remove to a plate.
Cook the chicken: Add remaining oil to the skillet.
Sear chicken in a single layer for 4–5 minutes, flip, and cook another 3–4 minutes until browned and cooked through.
Add salsa: Stir in salsa and simmer 1–2 minutes to glaze the chicken and keep it juicy. Return peppers and onions to the pan and toss.
Assemble bowls: Divide rice/cauliflower rice into 4 meal prep containers. Add chicken mixture, black beans, and corn.
Top with cherry tomatoes and cilantro.
Finish and store: Let cool slightly before sealing. Add avocado, yogurt, lettuce, and lime the day you plan to eat to keep everything fresh.
