In a skillet over medium heat, cook the ground turkey or chicken until no longer pink, breaking it up with a spoon as it cooks.
Stir in the taco seasoning and cook for another 2-3 minutes. Remove from heat and set aside to cool slightly.
Prepare the Salad Ingredients
In a large mixing bowl, combine the shredded lettuce, cherry tomatoes, black beans, corn kernels, diced red onion, shredded cheddar cheese, diced avocado, chopped cilantro, and sliced black olives (if using).
Add the cooked ground turkey or chicken to the bowl and toss everything together until well combined.
Make the Dressing
In a small bowl, whisk together the plain non-fat Greek yogurt, lime juice, and taco seasoning until smooth and creamy.
Assemble the Salad
Pour the dressing over the salad and toss to coat evenly.
Serve
Divide the crushed tortilla chips among serving plates or bowls.
