Brown the Beef: Start by placing a large skillet over medium heat. Add the ground beef and break it apart with a spoon as it cooks. Stir often so it browns evenly. Cook until no pink remains and the meat looks fully cooked. Carefully drain off excess grease so the salad does not feel heavy.
Season the Meat: Sprinkle the taco seasoning over the cooked beef. Pour in the water listed on the seasoning packet. Stir everything together until the beef looks well coated. Let it simmer for several minutes, stirring now and then, until the liquid thickens and clings to the meat. Turn off the heat and set aside.
Prepare the Vegetables: While the beef finishes, chop the iceberg lettuce into bite size pieces and place it in a large serving bowl. Slice the tomatoes in half, dice the onion, and cut the olives if needed. Add all of them over the lettuce along with the shredded cheese.
Assemble the Salad: Spoon the warm taco meat over the salad base. Spread it out gently so the heat slightly softens the cheese without wilting the lettuce too much. This step helps the flavors blend without losing crunch.
Add Dressing and Crunch: Drizzle French dressing evenly over the salad. Start with less and add more as needed. Toss gently until everything looks lightly coated. Sprinkle crushed tortilla chips over the top right before serving so they stay crisp.
