Place one tortilla on an oiled griddle or skillet over medium heat. Sprinkle 1/4 cup cheese over tortilla and top with 1/2 cup chicken mixture and 2 tablespoons cheese. Lay another tortilla on top and, when bottom tortilla has browned, flip quesadilla and cook until browned on other side and cheese is melted.
Repeat process with remaining tortillas, making 6 quesadillas. Cool slightly and cut into wedges. Serve each quesadilla with 2 tablespoons sour cream sauce.
