In a skillet over medium heat, add the ground beef. Cook for about 5-7 minutes, breaking it apart with a spatula until browned and fully cooked. This step ensures the meat is flavorful and safe to eat.

Drain any excess fat from the skillet. Add the taco seasoning and follow package instructions, usually adding a bit of water and simmering for a few minutes. This will infuse the meat with spices and enhance the overall flavor of the salad.

In a large mixing bowl, combine the chopped romaine lettuce, halved cherry tomatoes, black beans, corn, and shredded cheddar cheese. Toss gently to mix the ingredients evenly. This creates a colorful and nutritious base for your taco salad.

In a small bowl, whisk together the Catalina dressing, lime juice, and chili powder until well combined. This dressing adds a sweet and tangy flavor that complements the salad perfectly.

Add the cooked ground beef to the salad mixture and toss gently to combine. This ensures that the warm beef is evenly distributed throughout the salad.

Drizzle the Catalina dressing over the salad and toss again to coat all ingredients. This step is crucial for ensuring every bite is flavorful.

Top the salad with sliced avocado and crushed tortilla chips for added texture and flavor. Serve immediately for the best crunch.
