Dorito Casserole

Gather all ingredients.

Preheat oven to 350 degrees F (175 degrees C). Lightly grease a 3-quart baking dish with nonstick spray.

Cook ground beef in a very large skillet over medium heat until browned; drain any excess grease.

Add onion and pepper and continue cooking until tender, about 5 minutes.

Add taco seasoning and water. Simmer mixture until thickened, about 5 minutes.

Stir in diced tomatoes, sour cream, and black beans.

Sprinkle 1 1/2 cups crushed chips in the bottom of the prepared dish.

Evenly spoon about half of the meat mixture over the chips.

Top with 1 ½ cups crushed chips and 1 1/2 cups cheese.

Repeat with remaining meat, chips, and cheese.

Bake in the preheated oven until melted and bubbly, about 25 minutes.

Top with diced tomato, green onion, and cilantro and serve with salsa and additional sour cream.
