Preheat your oven to 350 degrees F. Spread ½ cup of the enchilada sauce in the bottom of a 13 x 9 baking dish.
Toss together the shredded beef and green chiles in a medium bowl.
Wrap the stack of 8 tortillas in dampened paper towels and microwave for 1 minute.
Evenly distribute beef mixture down the center of each tortilla. Sprinkle shredded cheese over each tortilla (reserve HALF of the cheese for topping).
Wrap tortillas tightly and place seam-side down into the baking dish.
Pour the remaining enchilada sauce over the tortillas, then sprinkle with the remaining shredded cheese.
Bake (uncovered) for 20 to 25 minutes, or until cheese is melted and sauce is bubbling around the edges of dish.
Top with desired toppings.
