Cut each breast into nuggets approximately 1 1/2 inches in diameter. Combine bread crumbs, cheese and seasonings in a plastic freezer bag. Dip nuggets into melted butter (if butter begins to cool and congeal, reheat slightly) and shake in crumb mixture. Place in single layer on baking sheets and freeze. When frozen, transfer to plastic freezer bags. To serve, place frozen nuggets on baking sheets and cook for 14 minutes at 400°. Serve with sweet and sour sauce. Makes 80 nuggets.
