Preheat your air fryer to 400°F (200°C).
Cut the chicken breast into 1-inch cubes and dice the bell peppers and red onions.
In a large bowl, toss the chicken, peppers, and onions with olive oil, chili powder, cumin, garlic powder, sea salt, and black pepper until evenly coated.
Place the mixture in a single layer in the air fryer basket.
Air fry for 12 to 15 minutes, shaking the basket halfway through, until the chicken is golden and reaches an internal temperature of 165°F.
While the chicken is cooking, warm the pre-cooked rice and rinsed black beans in a small pot or microwave.
Remove the chicken and vegetables from the air fryer and immediately drizzle with fresh lime juice.
Assemble the bowl by placing the rice and beans at the bottom, then topping with the chili-lime chicken mixture, sliced avocado, and chopped cilantro.
