The best Chicken Quesadea I've ever had

The best Chicken quesadilla I've ever had was at Chipoltle. It has plenty of chicken, plenty of Mozzarella cheese, and is really good. It's all nice and crispy, and has a delicious taste. I think they add a special ingredient in the Quesadilla. That's why Chipoltle's Chicken Quesadilla is delicious.
