1 lb ground beef

1 medium onion, chopped

1 can (15 oz) corn, drained

1 can (15 oz) diced tomatoes, drained

1 can (4 oz) green chilies, drained

1 can (10.5 oz) cream of mushroom soup

1/2 cup sour cream

1 bag (about 30 oz) frozen tater tots

1 1/2 cups shredded cheddar cheese

1/2 teaspoon garlic powder

1/2 teaspoon onion powder

Salt and pepper to taste

Preheat oven to 350°F (175°C).
In a large skillet, cook ground beef and chopped onion over medium heat, breaking up the meat as it cooks. Cook until the beef is browned and the onion is tender, about 7-8 minutes. Drain excess fat.
Stir in the drained corn, diced tomatoes, green chilies, cream of mushroom soup, sour cream, garlic powder, onion powder, salt, and pepper. Cook for another 2-3 minutes until well combined.
Spread the meat mixture evenly in a 9×13-inch baking dish.
Layer frozen tater tots over the top of the casserole.
Sprinkle shredded cheddar cheese over the tater tots.
Bake for 30-35 minutes, or until tater tots are golden brown and cheese is bubbly.
Let cool for a few minutes before serving.

You can add extra veggies like bell peppers or mushrooms for more texture and flavor.

For a lighter version, substitute ground turkey or chicken for the beef.

Try different cheese combinations like mozzarella and Monterey Jack for a twist on the flavor.
