01 - Heat a large skillet over medium heat. Add ground beef and cook until fully browned, breaking it apart with a wooden spoon. Drain excess fat.
02 - Add taco seasoning and water to the browned beef. Stir well and simmer for 2–3 minutes, allowing the mixture to thicken. Remove from heat and let 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 - Top the salad mixture with the slightly cooled taco beef.
05 - Right before serving, add the crushed Doritos chips and your choice of ranch or Catalina dressing. Toss gently to combine, ensuring even distribution of ingredients.
06 - Serve immediately while chips maintain their crisp texture.
