Easy peasy chicken quesadillas

2 cups chicken, chopped (great way to use up leftovers!)
3/4 cup ranch dressing
1 packet taco seasoning
2 cups Mexican blend cheese, shredded
6 large flour tortillas

Mix together chicken, taco seasoning, ranch dressing, and cheese.
Heat pan on medium and coat with cooking spray.
Put 1 tortilla on the bottom in the pan, 1 layer of chicken mixture, then top with another tortilla.
Brown one side, then carefully flip to brown other side. Cut into 1/4s and serve hot.
