Prepare the seasoning and chicken: Mix all the burrito seasoning ingredients together. Drizzle 1 tablespoon of olive oil over the chicken and toss to coat. Sprinkle the seasoning evenly and mix until the chicken is fully coated.
Cook the chicken: Heat 1 tablespoon of olive oil in a large skillet over high heat. Add the chicken and cook for about 2 minutes on one side, then 1.5 minutes on the other. Remove the chicken and let it rest for 2 minutes. Chop into bite-sized pieces.
Sauté the vegetables: In the same skillet, add chopped onion and garlic. Cook for 1 minute until fragrant. Add diced red bell pepper (capsicum) and cook for 2 minutes until the onion becomes translucent.
Finish the chicken filling: Add refried beans, chopped chicken, and 1/4 cup water. Stir and cook for about 2 minutes until slightly thickened. The filling should be thick, juicy, and not watery or dry. Let it cool for 5 minutes—it will continue to thicken, making it perfect for rolling.
Warm the tortillas: Gently heat the tortillas in the microwave to make them flexible. Lay them flat on your work surface.
Assemble the burritos: Place cooked rice on the lower third of each tortilla. Add the chicken filling, corn, shredded cheese, and sprinkle with chopped cilantro. Fold the sides over and roll up burrito-style.
