Heat a large nonstick skillet over medium high heat, when the pan is hot place 1/3 cup cheese directly into the pan and spread out into a 5 in circle. Spoon on some of the mushroom mixture into the center of the cheese. Let the cheese melt and bubble, when the edges begin to look crisp place a charred tortilla on top and with a spatula press down firmly. With a spatula carefully flip the quesadilla over so the cheese is facing up. Remove from the pan and fold in half, place the quesadilla into the oven to keep warm while you finish the remaining quesadillas
