01 - Preheat oven to 400°F. Line a baking sheet with parchment paper or lightly oil it.
02 - In a large bowl, combine ground chicken, egg, breadcrumbs, garlic, green onions, onion powder, smoked paprika, salt, and pepper. Mix gently until just combined.
03 - With damp hands, form the mixture into 20 small meatballs and place them on the prepared baking sheet.
04 - Bake for 18-20 minutes, or until meatballs are golden and cooked through (internal temperature should reach 165°F).
05 - While the meatballs bake, prepare the buffalo sauce: In a small saucepan over low heat, melt butter. Whisk in hot sauce, Worcestershire sauce, and garlic powder until smooth. Remove from heat.
06 - Transfer cooked meatballs to a large bowl. Pour buffalo sauce over the meatballs and toss gently to coat evenly.
07 - Arrange meatballs on a serving platter. Sprinkle with crumbled blue cheese and fresh chives or parsley, if using. Serve with celery and carrot sticks.
