Heat olive oil in a skillet over medium-high heat.
Add chicken strips and cook until browned and cooked through, about 5-7 minutes.
Add bell peppers, onion, and garlic to the skillet. Cook until vegetables are tender, about 5 minutes.
Stir in chili powder, cumin, and paprika. Cook for another 2 minutes.
Assemble the bowls by dividing the cooked rice, black beans, and corn among four bowls.
Top with the chicken and vegetable mixture.
Garnish with lime wedges, salsa, shredded cheese, sour cream, and avocado slices.
