Bring a large pot of salted water to a rolling boil. Cook rotini or penne pasta until al dente (about 8-10 minutes). Drain and rinse under cold water.

In a medium-sized bowl, whisk together Greek yogurt, BBQ sauce, and light mayo. Season with salt and pepper to taste.

In a large mixing bowl, combine cooled pasta, shredded grilled chicken, rinsed black beans, corn, diced red onion, chopped celery, and fresh cilantro.

Pour the dressing over the combined ingredients and gently fold to coat everything.

Cover the bowl and chill in the refrigerator for at least 30 minutes.

Stir before serving and garnish with extra cilantro if desired. Serve chilled.
