In a mixing bowl, combine the olive oil, garlic powder, onion powder, smoked paprika, ground cumin, salt, and pepper. Mix well to create a flavorful seasoning blend. Rub this mixture evenly over both chicken breasts.
Heat a non-stick skillet over medium heat. Once hot, add the seasoned chicken breasts. Cook for approximately 6-7 minutes per side, or until the chicken is golden brown and reaches an internal temperature of 165°F (75°C). Remove from heat and let the chicken rest for 5 minutes before slicing it into thin strips.
In a separate skillet, lightly warm each flour tortilla for about 20-30 seconds on each side until they are soft and pliable.
Place a warmed tortilla flat on a clean surface or plate. Begin layering the fillings: start with a scoop of brown rice, followed by black beans, corn kernels, diced tomatoes, shredded lettuce, and the sliced avocado. Top with a generous portion of the cooked chicken strips.
Drizzle a plentiful amount of Chipotle Ranch dressing over the layered fillings.
Fold the sides of the tortilla inward, then carefully roll it up tightly from the bottom to form a secure burrito. Repeat the assembly process for the remaining tortillas.
Cut each burrito in half diagonally and arrange them on a serving platter. Garnish with freshly chopped cilantro on top.
Notes
Serve with extra Chipotle Ranch dressing on the side for dipping.
