Grease a 13 x 9 inch baking dish, and set aside.
In a large skillet, cook the ground beef, garlic and onion until meat is no longer pink. Drain if needed. Add the salsa, beans, enchilada sauce, chilies, taco seasoning and pepper, stir often.
To build the lasagna, spread 1 cup meat mixture in the 13 x 9 baking dish. Next, layer with two tortillas, a third of the meat mixture and 1 cup cheese. Repeat layers. Top with the remaining tortillas and meat mixture.
Cover and bake at 375 for 30 minutes. Uncover, sprinkle with the remaining cheese and top with tortilla chips. Bake another 10-15 minutes or until the cheese is melted.
Let stand for 5-10 minutes before serving. Serve with optional sides like guacamole and sour cream.
