1 pound ground beef
1 small onion, chopped
1 teaspoon garlic, minced
½ teaspoon garlic salt
2 tablespoons taco seasoning, or your favorite taco seasoning package
1 can black beans, drained and rinsed
1 cup corn, frozen
4 ounce can green chilies
9.25 ounces corn chips, reserve out ½ cup for topping
2 cups sour cream
24 ounces salsa, your favorite style
2 cups cheddar cheese
olives, chopped tomatoes, shredded lettuce, green onions, additional sour cream, crushed corn chips (optional serving toppings)

Preheat the oven to 350°F. Spray the bottom of a 9x13-inch pan with nonstick spray.
In a large skillet, brown the ground beef with the chopped onions and garlic. Drain off any extra grease.
Add the garlic salt and taco seasoning to the meat and stir to mix.
Stir in the beans, corn, and green chilies and stir until heated through. Set aside.
Fill the bottom of the pan with corn chips.
Spoon the ground beef mixture over the chips.
Drop the sour cream by spoonfuls over the meat mixture and spread around.
Pour the salsa over the sour cream. Sprinkle the cheese over the top.
Bake for 30 minutes or until cheese melts.
Remove from the oven and let sit for 10 minutes before serving.

If you want to increase the spiciness, you can use spicy salsa or add 1 teaspoon of chili powder.
Prepare this dish ahead of time, simply assemble and place in the fridge or freezer until you are ready to bake.
For an even quicker cooking time, the ground beef and onions can be cooked ahead of time. Store in the refrigerator for up to 3 days or in the freezer for up to a month.
