Heat a tablespoon of oil in a large skillet over medium-high heat for 1-2 minutes.

Add the diced boneless, skinless chicken breasts and cook for 5-7 minutes until browned and cooked through.

Stir in the chopped onions and minced garlic, sautéing for 1-2 minutes until fragrant, then add the bell peppers and cook for another 3-4 minutes.

Mix in the black beans along with cumin and chili powder, cooking for an additional 5 minutes.

Taste and adjust seasoning as needed, then garnish with cilantro and lime wedges before serving.
