01 - In a large skillet over medium heat, cook the ground beef until thoroughly browned, using a wooden spoon to break up the meat as it cooks. Drain off any excess fat.
02 - Stir in the taco seasoning and water. Simmer for 2 to 3 minutes, stirring occasionally, until the mixture thickens. Remove the skillet from heat and allow the beef to cool slightly.
03 - In a large salad bowl, combine the chopped romaine lettuce, cherry tomatoes, diced red onion, black beans, corn, and shredded cheddar cheese.
04 - Add the slightly cooled taco beef to the salad bowl with the vegetables and cheese.
05 - Just before serving, add the slightly crushed Doritos and your preferred dressing. Gently toss until all ingredients are evenly coated.
06 - Serve immediately to preserve the crunch of the Doritos.
