In a skillet over medium heat, brown 1 pound of ground beef for about 6-8 minutes, breaking it apart with a spatula until no longer pink. Stir in taco seasoning and cook for another minute until well-coated. Remove from heat and set aside.

Chop 4 cups of iceberg lettuce into bite-sized pieces and dice 2 medium tomatoes. If using block cheese, shred about 1 cup of cheddar cheese. In a large mixing bowl, combine the lettuce, tomatoes, and cheese.

Once the beef has cooled slightly, add it to the bowl and gently toss everything together.

Just before serving, lightly crush 2 cups of nacho cheese Doritos and sprinkle them over the salad.

Drizzle your desired amount of dressing over the salad and toss gently to mix.
