Preheat oven to 350°F. Spray a 13 x 9 casserole dish with nonstick spray; set aside.
In a large skillet, add ground beef, and onions. Cook over medium heat until beef is browned. Drain any excess grease. Once grease is drained, add taco seasoning, stir, and set aside.
Add beef to the casserole dish, and rinsed pinto beans. Carefully pour over the enchilada sauce. Top with ¾ of the shredded cheese, and then cover the cheese with chips. Add the rest of the cheese.
Bake for 12-15 minutes until cheese is melted. Allow casserole to sit for 5 minutes before serving.
Garnish with green onions, sour cream, lettuce, guacamole, and black olives- enjoy!
