Preheat oven to 375°F (190°C) and grease a 9x13 baking dish.
In a large bowl, mix shredded chicken, 1 cup of cheese, green chiles, garlic powder, and cumin.
Spread a small amount of enchilada sauce on the bottom of the dish.
Layer 3–4 tortillas, half of the chicken mix, sauce, and repeat. Top with remaining sauce and cheese.
Cover with foil and bake for 20 minutes.
Uncover and bake an additional 10 minutes until cheese is bubbly.
Let rest 10 minutes before serving. Garnish as desired.
