Follow these detailed steps to create your BBQ Chicken Quesadilla:

1. Prepare Chicken: In a large bowl, mix the shredded chicken with BBQ sauce until well coated. If desired, you can adjust the amount of sauce to your taste.

2. Heat the Pan: In a large skillet, heat 1 tablespoon of olive oil over medium heat. Make sure the oil coats the bottom evenly.

3. Assemble Quesadilla: Place one tortilla in the heated skillet. On one half of the tortilla, add about ½ cup of the BBQ chicken mixture and ¼ cup of shredded cheese.

4. Fold the Tortilla: Carefully fold the tortilla in half, covering the filling. Cook for 3-4 minutes or until the bottom is golden brown.

5. Flip Quesadilla: Use a spatula to flip the quesadilla gently. Cook the other side for another 3-4 minutes, until it is crispy and the cheese is melted.

6. Remove and Repeat: Transfer the cooked quesadilla to a plate. Repeat the process with the remaining tortillas and filling.

7. Slice Quesadilla: Once all quesadillas are cooked, let them cool for a few minutes. Then, slice each into wedges for easy serving.

8. Garnish: If desired, sprinkle chopped green onions on top for added flavor and garnish.
