01 - Heat a large skillet over medium heat. Add the ground beef and cook, breaking it apart with a wooden spoon or spatula, until fully browned. Drain any excess fat.
02 - Stir in taco seasoning and 1/4 cup water. Simmer for 2 to 3 minutes until the mixture thickens, then remove from heat and allow to cool slightly.
03 - In a large salad bowl, combine chopped romaine lettuce, halved cherry tomatoes, diced red onion, black beans, corn, and shredded cheddar cheese.
04 - Add the slightly cooled taco beef to the vegetable and cheese mixture.
05 - Just before serving, add crushed Doritos and your choice of dressing. Toss gently until evenly combined.
06 - Serve immediately while the Doritos are still crunchy.
