In a large skillet over medium heat, cook the ground beef until browned, breaking it apart with a spatula.
Add the taco seasoning and follow the package instructions (usually by adding water and simmering until thickened).
Remove from heat and let it cool slightly.
2. Prepare the Salad Base:
In a large salad bowl, add the chopped iceberg lettuce.
Add the halved cherry tomatoes, shredded cheddar cheese, sliced black olives, diced red onion, and sliced cucumber.
Add the seasoned ground beef to the salad.
Sprinkle the crushed Doritos over the top.
Add dollops of sour cream and salsa on top.
Gently toss everything together until evenly mixed.
Serve immediately and enjoy!
