To make this salad, start by preparing the dressing. Add all of the dressing ingredients (the greek yogurt, cottage cheese, olive oil, lemon juice, dried dill, dried parsley, garlic powder, onion powder, and kosher salt) to a blender.
Blend the dressing until it's smooth and creamy. Taste and adjust the seasonings as needed, then set it aside.
Next, prepare the chicken by cutting it into bite-sized pieces. Add the pieces to a bowl and toss them in the barbecue sauce.
Heat a cast iron skillet, on the stove, over medium-high heat and add in one tablespoon of olive oil.
Once the oil is hot, add in the chicken and allow it to cook for 8-9 minutes, or until it's cooked through and reaches an internal temperature of 165 F. Sauté frequently, so that the chicken doesn't stick to the pan.
While the chicken is cooking, prepare the salad. Wash and chop the romaine lettuce, and add it to a bowl.
Drain and rinse the corn and black beans, then add them to the bowl with the lettuce.
Finally chop the baby tomatoes, cilantro, and green onions, and add them to the salad bowl alongside the corn chips (if using).
Add the cooked chicken to the salad, pour the dressing on top, then toss to fully combine.
Serve the salad immediately and enjoy! Store any leftovers in an airtight container, in the fridge, for up to three days.
