01 - In a large skillet over medium heat, cook ground beef, breaking it up with a spoon until thoroughly browned. Drain off any excess fat.
02 - Stir taco seasoning and water into the cooked beef. Simmer for 2 to 3 minutes, allowing the mixture to thicken. Remove from heat and let 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 - Gently fold the slightly cooled taco beef into the salad mixture.
05 - Just before serving, add the slightly crushed Doritos and your choice of ranch or Catalina dressing. Toss the salad gently until evenly combined.
06 - Serve immediately to ensure the chips remain crisp and the salad is at its best.
