Prep the Ingredients: Start by chopping the chicken into bite-sized pieces, dicing the bell peppers and onion, and mincing the garlic.
Sauté the Aromatics: In a large skillet, heat olive oil over medium heat. Add the chopped onions and garlic, cooking until fragrant, about 2 minutes.
Cook the Chicken: Add the chicken pieces to the skillet along with cumin, chili powder, salt, and pepper. Stir occasionally, cooking until the chicken is lightly browned on all sides (about 5-7 minutes).
Add Rice & Liquid Ingredients: Stir in uncooked rice, diced tomatoes (with juice), black beans, and a bit of water or broth. Bring everything to a simmer.
Cook Until Tender: Cover the skillet and reduce the heat to low. Let it cook for about 20 minutes or until the rice is tender and the flavors have blended.
Garnish & Serve: Fluff the rice with a fork and top with cilantro or lime juice. Serve with avocado slices or shredded cheese if desired.
