In a large skillet over medium heat, add the ground beef. Cook for about 7-10 minutes until browned and no longer pink, stirring occasionally, then drain excess grease.

Return the skillet to medium heat and add taco seasoning with a splash of water. Stir continuously for another 2-3 minutes.

In a large mixing bowl, combine the seasoned beef with chopped lettuce, diced tomatoes, and shredded cheese. Toss gently.

Cover with plastic wrap and refrigerate for at least 15-30 minutes.

When ready to serve, drizzle dressing over the mixture and toss gently.

Right before serving, gently fold in the crushed Doritos.
