Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Combine sliced chicken breasts, bell peppers, and red onion in a large bowl.
Drizzle the mixture with olive oil and toss to coat evenly.
Sprinkle the chicken and veggies with chili powder, cumin, garlic powder, paprika, salt, and pepper. Toss again until everything is well-seasoned.
Spread the chicken and vegetable mixture in a single layer on the prepared baking sheet.
Bake in the oven for 20-25 minutes or until the chicken is cooked and the vegetables are tender and slightly charred.
While the fajita mix is baking, prepare the brown rice according to the package instructions if not already cooked.
In a separate bowl, mix the black beans and corn. Heat them if desired.
To assemble the bowls, divide brown rice among four serving bowls.
Top the rice with the baked chicken fajita, black beans, and corn.
Garnish with fresh cilantro and serve with lime wedges on the side.
Add toppings, such as avocado, cheese, sour cream, or salsa, as desired.
