These barbecued chicken and avocado quesadillas are a delicious twist on the classic Mexican dish. The combination of tender, smoky chicken, creamy avocado, and melted cheese is simply irresistible. The chicken is marinated in a tangy barbecue sauce, then grilled to perfection before being stuffed into a tortilla with avocado slices and cheese. The quesadillas are then cooked until golden and crispy, resulting in a mouthwatering meal that is perfect for lunch or dinner.
