Follow these easy steps to create your Loaded BBQ Chicken Quesadillas:

1. Preheat the Skillet: Heat a large skillet over medium heat and add 1 tablespoon of olive oil.
2. Prepare Chicken Mixture: In a mixing bowl, combine the shredded chicken with BBQ sauce, bell peppers, and red onion. Mix until everything is well-coated.
3. Assemble Quesadillas: Place a tortilla in the skillet and sprinkle half of it with a generous amount of shredded cheese. Top with a portion of the chicken mixture, then add some more cheese on top.
4. Fold and Cook: Fold the tortilla over, creating a half-moon shape. Press gently with a spatula. Cook for 3-4 minutes on each side until golden and the cheese is melted.
5. Repeat Process: Continue with the remaining tortillas and filling, adding more oil to the skillet as needed.
6. Cut and Serve: Once cooked, remove quesadillas from the skillet and let them rest for a minute. Cut into wedges and serve with desired toppings.

The step-by-step process is straightforward, allowing even novice cooks to create this dish with ease.
