Start by browning your beef with your favorite taco seasoning and setting aside to cool.
In a large bowl, add lettuce, tomatoes, olives, black beans, and shredded cheese (along with any other toppings you desire).
Crush up a half bag of Doritos and pour over top of the taco salad mixture.
Add browned taco meat on top, then pour 1-2 cups of French or Catalina Dressing on top.
Toss the salad gently to combine all ingredients and serve immediately.
**If not serving immediately, skip adding the dressing until ready to serve. If you don't think you'll eat the whole salad in one sitting, leave the dressing on the side to be poured on individually.
