Heat the oil over medium heat in a small pan. Place tortillas in the hot oil, one at a time, for 10 seconds on each side. Transfer to a paper towel to drain.
Add sauce to the the bottom of a baking dish. Place 3-4 tablespoons of cheese to each tortilla, roll up and place in the dish or add a layer tortillas, topped with a layer of cheese, then more tortillas.
Cover the enchiladas with sauce and top with the remaining shredded cheese. Bake at 350 degrees for 20-25 minutes. Serve with your favorite toppings!
