Heat the olive oil in a skillet over medium heat. Add the ground beef and stir in the taco seasoning, salt, and pepper. Cook until browned and fully cooked, about 7-8 minutes. Drain any excess grease, and set aside to cool slightly.
For the dressing, whisk together Greek yogurt, salsa, lime juice, olive oil, chili powder, cumin, salt and pepper. Taste and adjust seasoning as needed, then refrigerate until ready to serve.
Start assembling the salad in a large serving bowl, serving platter, or individual plates. Begin with the romaine, followed by the cherry tomatoes, sweet corn, black beans, red onion, avocado, and shredded cheddar cheese.
Add the cooked ground beef to the salad. Sprinkle the crushed tortilla chips over the top for crunch.
Serve the salsa-yogurt dressing on the side, so each person can add their preferred amount.
Serve immediately and enjoy!
