Step 1

Preheat oven to 350°F.

Step 2

Brown ground beef, onion and garlic in a large, oven-proof skillet over medium high heat until beef is no longer pink (about 5-7 minutes). Drain and return beef mixture to the skillet.

Step 3

Stir in chili powder, beans and tomatoes. Simmer for about 5-10 minutes to allow the flavors to come together and the liquid to thicken slightly. Season with salt and pepper, to taste.

Step 4

Sprinkle grated cheddar over top. Top with corn chips.

Step 5

Bake, uncovered, for about 15-20 minutes (or until the casserole is warm and the cheese is melted). Garnish with optional toppings and serve immediately.
