In a skillet over medium heat, cook the ground beef until browned, about 5-7 minutes.

Drain excess fat and add taco seasoning and water. Stir and simmer for 5 minutes.

In a large mixing bowl, combine the romaine lettuce, cherry tomatoes, black beans, corn, cheddar cheese, and avocado.

Add the cooked beef mixture on top of the salad.

In a small bowl, mix together sour cream, salsa, and lime juice until well combined.

Drizzle the dressing over the salad and toss gently to combine.

Divide the salad among serving plates and enjoy!
