PREHEAT oven to 425ºF (220ºC). Mix chicken, Buffalo Wings Sauce, mozzarella and green onion in medium bowl.
DIVIDE dough evenly into small balls, about the size of a golf ball. Gently flatten 1 piece of dough into round disc in palm of hand. Place about 1 heaping teaspoon of the chicken mixture in center of disc. Pinch dough together to enclose filling, forming a ball. Repeat with remaining dough and filling. Arrange bombs on large parchment-lined baking sheet. Brush bombs with olive oil.
BAKE 20 to 25 minutes or until golden brown.
TRANSFER Buffalo Chicken Bombs to serving platter. Sprinkle with bleu cheese crumbles and drizzle with additional Buffalo Wings Sauce. Serve with bleu cheese dressing and celery or carrot sticks, if desired.
