Creating BBQ Chicken Quesadillas is a simple process. Follow these steps to achieve perfect results:

1. Prepare the Chicken: In a bowl, combine the shredded chicken with the BBQ sauce, mixing well to coat the chicken evenly.
2. Heat the Skillet: Place a large skillet over medium heat and add olive oil.
3. Assemble the Quesadillas: Lay one tortilla in the skillet. Sprinkle half of the cheddar and mozzarella cheese over the tortilla.
4. Add Chicken: Spoon half of the BBQ chicken mixture evenly over the cheese.
5. Layer More Cheese: Top with additional cheese, then place a second tortilla on top.
6. Cook: Cook for about 3-4 minutes or until the bottom tortilla is golden brown. Carefully flip the quesadilla and cook for another 3-4 minutes until both sides are crispy.
7. Repeat: Remove the cooked quesadilla from the skillet and place it on a cutting board. Cut into wedges. Repeat the process for the remaining tortillas and filling.
8. Serve: Garnish with fresh cilantro and serve with sour cream on the side.
