Creating Pollo Asado Quesadillas Rellenas is straightforward. Follow these simple steps:

1. Marinate the Chicken: In a bowl, mix olive oil, lime juice, chili powder, cumin, garlic powder, onion powder, salt, and pepper. Add the chicken thighs and coat well. Marinate for at least 15 minutes.

2. Cook the Chicken: Preheat a grill or skillet over medium-high heat. Cook the marinated chicken for about 6-7 minutes per side, or until fully cooked and charred. Remove, and let it rest for a few minutes.

3. Shred the Chicken: Once cooled, shred the chicken using two forks or your hands.

4. Sauté Vegetables (Optional): In the same skillet, add diced bell peppers and onions. Sauté for about 3-4 minutes until they are softened and fragrant.

5. Assemble Quesadillas: Lay one tortilla flat, and sprinkle half with cheese, then arrange shredded chicken and sautéed veggies. Top with additional cheese and fold the tortilla.

6. Cook Quesadillas: Wipe the skillet clean and return to medium heat. Place the folded tortilla in the skillet and cook until golden brown, about 3-4 minutes. Flip and cook the other side until the cheese is melted.

7. Repeat the Process: Continue with the remaining tortillas until all quesadillas are cooked.

8. Slice and Serve: Remove from the skillet, and slice into wedges.
