Preheat a sandwich press or use a frying pan over medium heat. Place a tortilla on the base plate. Spread about ½ cup of the hot mixture over one half of the tortilla. Sprinkle with grated cheese and fold over to enclose the filling. Cook for 3–4 minutes or until the quesadilla is crispy and hot, turning once if cooking in a frying pan. Repeat for the remaining tortillas. Cut into wedges and serve with salad greens.
