In a large skillet, cook your ground meat over medium heat until no longer pink. Drain excess grease.
Stir in the tomato sauce, beans, corn, chopped chilies, onion, cumin, garlic powder, and oregano; heat through.
In an 11x7 or 13×9 baking dish coated lightly with avocado oil or cooking spray, layer half of the tortillas on the bottom, then evenly cover with half your beef mixture and cheese. Repeat layers.
Bake, uncovered, at 350 degrees f. for 25-30 minutes or until hot and bubbly.
Enjoy!
