In a medium bowl, combine buffalo sauce, Greek yogurt, olive oil, garlic, smoked paprika, onion powder, black pepper, cayenne pepper, and sea salt. Mix until combined.
Add the diced chicken to the bowl and mix until the chicken is completely coated in the sauce.
In a medium skillet over medium heat, add the chicken mixture and cook for 8-10 minutes, stirring frequently, until the chicken is cooked through and the sauce has thickened.
Remove the skillet from the heat and stir in the celery, red onion, and parsley.
Place the mushroom caps on a large baking sheet and fill each mushroom cap with the chicken mixture.
Bake for 15-20 minutes, or until the mushrooms are cooked through.
Serve warm and enjoy!
