01 - In a large skillet over medium heat, cook the ground beef, breaking it apart with a wooden spoon, until browned throughout. Drain any excess fat.
02 - Add taco seasoning and water to the skillet. Stir to combine and simmer for 2 to 3 minutes, or until the mixture thickens. Remove from heat and allow to cool slightly.
03 - In a large salad bowl, combine chopped romaine lettuce, cherry tomatoes, diced red onion, black beans, corn, and shredded cheddar cheese.
04 - Add the slightly cooled, seasoned ground beef to the bowl with the vegetables and cheese.
05 - Just before serving, add the crushed Doritos and your choice of dressing. Toss gently until all components are evenly combined.
06 - Serve immediately while the salad is still crisp and the chips retain their crunch.
