In a large mixing bowl, combine the shredded chicken, Greek yogurt, and buffalo sauce. Stir until the chicken is evenly coated.
Add the celery, red onion, garlic powder, onion powder, paprika, salt, and black pepper. Mix well to incorporate all the flavors.
Stir in the fresh parsley and green onions for an extra pop of freshness.
Taste and adjust seasoning if needed.
Serve immediately, or refrigerate for at least 30 minutes for the flavors to meld together.
Enjoy on its own, in a wrap, on a sandwich, or over a fresh green salad.
