Step 1: Cook the Chicken : Heat olive oil in a large skillet over medium-high heat. Add the diced chicken and sprinkle with chili powder, cumin, paprika, garlic powder, onion powder, salt, and pepper. Cook for 6–8 minutes, stirring occasionally, until chicken is golden and cooked through. Remove from heat and set aside.
Step 2: Prepare the Burrito Mixture : In a large bowl, combine cooked chicken, rice, black beans, corn, bell peppers, onions, cilantro, and lime juice. Mix well until everything is evenly distributed and flavorful.
Step 3: Assemble the Quesadillas : Lay out a tortilla on a flat surface. Sprinkle 1/4 cup of shredded cheese on one half of the tortilla. Add a generous layer (about 1/2 cup) of the chicken burrito filling on top. Sprinkle another layer of cheese on top of the filling (this helps it stick). Fold the tortilla over to form a half-moon shape. Repeat with remaining tortillas and filling.
Step 4: Cook the Quesadillas Heat a large nonstick skillet or griddle over medium heat and melt 1/2 tablespoon butter or oil. Place one quesadilla in the skillet and cook for 2–3 minutes per side until golden brown and the cheese has melted. Remove from heat and repeat for remaining quesadillas. Slice each quesadilla into wedges.
Step 5: Make the Salsa (Optional but Delicious) : In a small bowl, combine diced tomatoes, onion, jalapeño, cilantro, lime juice, and salt. Mix and set aside for serving.
