In a large skillet over medium heat, cook 1 pound of ground beef or turkey until browned, about 6-8 minutes. Use a spatula to break it up as it cooks. Stir in 2 tablespoons of taco seasoning and follow package instructions, adding water if necessary. Cook for an additional 2-3 minutes.

While the meat cools, wash and chop 4 cups of lettuce into bite-sized pieces and place it in a large mixing bowl. Dice 1-2 ripe tomatoes and thinly slice half an onion.

Begin layering the salad in the large bowl or individual serving dishes. Start with the chopped lettuce as the base, followed by the seasoned meat, then add the diced tomatoes and sliced onions.

Generously sprinkle a bag of Doritos over the layered salad for crunch. Choose between nacho cheese or cool ranch flavors.

Serve immediately to maintain the crunchiness of the Doritos. Place dressings on the side, allowing guests to customize their salads.
