Start by removing the skin and bones from the rotisserie chicken. Shred the chicken finely and set aside in a large mixing bowl.

In a medium bowl, combine Greek yogurt, mayonnaise, and buffalo hot sauce. Add garlic powder and smoked paprika, blending until smooth.

In the bowl with shredded chicken, add celery, carrot, red onion, and chives. If using, fold in blue cheese crumbles. Toss gently until coated.

Serve immediately in lettuce wraps or on whole-grain bread, or chill for at least 30 minutes for enhanced flavor.
