Season the chicken with olive oil, spices, salt, pepper, and lime juice. Let it sit for 15–30 minutes.
Cook the chicken in a skillet or grill pan over medium heat until fully cooked (about 5–7 minutes per side). Slice into strips or cubes.
Prepare the base by cooking rice according to package instructions.
Warm the beans and corn (optional, but improves flavor).
Assemble the bowl: add rice first, then chicken, beans, corn, lettuce, and tomatoes.
Top it off with cheese, avocado, and Greek yogurt or sour cream.
Serve immediately or portion into containers for meal prep.
