In a skillet over medium heat, cook the ground beef until browned. Drain excess fat, then stir in the taco seasoning and water. Simmer for about 5 minutes until thickened.

In a large bowl, combine the chopped romaine lettuce, cherry tomatoes, black beans, corn, and shredded cheddar cheese.

Add the cooked taco meat to the salad mixture and gently toss to combine.

Just before serving, add the crushed Doritos and drizzle with salsa and sour cream. Toss lightly to combine.

Serve immediately for the best crunch.
