Heat olive oil in a skillet over medium heat. Add the shredded chicken, chili powder, cumin, garlic powder, onion powder, and salt. Stir well and cook for 3-4 minutes until heated through.
Heat the tortillas in a dry skillet or microwave for a few seconds until warm and pliable. This helps prevent them from tearing when assembling the burritos.
Place each tortilla on a flat surface. Add a layer of rice, black beans, seasoned chicken, shredded cheese, salsa, and sour cream. Be careful not to overfill.
Fold in the sides of the tortilla, then roll it tightly from the bottom to create a burrito shape. Ensure the filling is secure inside.
