On one half of each tortilla, layer evenly all the ingredients in the order given.
Fold each tortilla over to create a "half moon" and press down lightly.
Coat the skillet or griddle with a light mist of cooking spray and warm to a medium-low heat. Cook each quesadilla for two to three minutes on each side until lightly browned and the cheese melts. Remove from pan and cut each into 3 wedges and serve with a light ranch dressing or salsa.
