Preheat your oven to 375°F (190°C).

Season the chicken breasts with olive oil, chili powder, cumin, garlic powder, paprika, salt, and pepper.

Heat a skillet over medium-high heat and cook the chicken for about 5-6 minutes on each side, until fully cooked. Once done, remove from heat and let it rest for 5 minutes before slicing into thin strips.

In a large bowl, mix the cooked rice, black beans, corn, diced avocado, shredded cheese, cilantro, and lime juice. Stir until everything is well combined.

Lay a tortilla flat. Add a layer of the rice and bean mixture, followed by sliced chicken.

Carefully fold the sides of the tortilla over the filling, then roll it up from the bottom, tucking in the edges as you go to form a burrito.

Repeat for the remaining tortillas.

Place the burritos on a baking sheet and bake for about 10-15 minutes until the tortillas are lightly crispy.

Remove from the oven and allow to cool slightly before serving.
