In a large bowl, combine ground chicken, breadcrumbs, egg, garlic, onion, onion powder, garlic powder, salt, pepper, and 1/3 cup buffalo sauce.
Use a cookie scoop and gently form into golf ball size rounds. Arrange on a cookie sheet lined with foil or parchment paper that has been lightly sprayed with oil.
Bake 18-20 minutes, or until internal temperature reads 160 F.
Remove from oven, toss in a bowl with remaining buffalo sauce.
Place on a serving platter, and drizzle with dressing and sprinkle with chives.
