In a large skillet over medium heat, brown the ground beef, breaking it into small crumbles until it’s no longer pink and evenly cooked, about 6-8 minutes. Drain any excess grease.

Return the skillet to heat and add taco seasoning according to packet instructions, usually adding some water and letting it simmer until thickened, around 5 minutes.

In a large mixing bowl, combine the cooled seasoned beef with the chopped lettuce, diced tomatoes, chopped onion, and shredded cheddar cheese. Gently mix until well-coated.

Cover the salad and refrigerate until ready to serve, ideally at least 15-30 minutes.

Just before serving, toss the salad with your choice of dressing and mix in the Doritos. Serve immediately for maximum texture contrast!
