Pre-heat oven to 350° F.
Lay tortilla chips over a baking sheet pan. Layer chicken fajitas over the tortilla chips and then layer cheese on top. Bake for about 15 minutes or until all the cheese is melted. Remove from oven and allow to cool for a few minutes. Top with your choice of toppings: guacamole, salsa, sour cream, jalapeños, chopped tomatoes and what ever your heart desires.
