Creating Pollo Asado Quesadillas Rellenas is easy if you follow these steps closely:

1. Marinate the Chicken: In a bowl, combine olive oil, adobo seasoning, garlic powder, cumin, and lime juice. Add chicken thighs and marinate for at least 20 minutes.

2. Cook the Chicken: Heat a skillet over medium heat. Add the marinated chicken and cook for about 6-7 minutes on each side until cooked through. Once done, remove from the skillet and let rest before shredding.

3. Sauté the Vegetables: In the same skillet, add the diced onion and bell pepper. Cook until softened, about 3-4 minutes. Combine the vegetables with the shredded chicken.

4. Assemble the Quesadillas: In a separate skillet, place one tortilla and sprinkle half of the shredded cheese evenly over one half. Spoon some of the chicken and vegetable mixture onto the cheese, then add additional cheese on top before folding the tortilla over.

5. Cook the Quesadillas: Cook on medium heat for 3-4 minutes on each side, or until crispy and golden brown. Repeat with remaining tortillas and filling. Cut each quesadilla into wedges before serving.
