Southwestern Bake

Preheat oven to 375 degrees F (190 degrees C). In a medium skillet over medium heat, brown the ground beef with the garlic and onion; drain. In a large mixing bowl, combine the meat mixture, chili powder, black beans, corn, sour cream and salsa. Stir until well blended. Into a 9x13 inch baking dish, spoon enough of the beef mixture to cover the bottom. Arrange half of the crushed tortilla chips on top of the meat mixture and layer with 1 cup of Cheddar cheese. Spoon another layer of the meat mixture on top of the cheese layer, cover with remaining chips and layer with 1 cup of cheese. Spread final layer of meat mixture on top and sprinkle the remaining 1 cup of cheese on top. Top with diced tomato and green onions. Bake in the preheated oven for 40 minutes. Let cool for 10 minutes before serving.
