MIX oil, ginger, garlic and garlic sauce. Mix 2/3 cup (or 1 Tbsp. for trial recipe) of the oil mixture with barbecue sauce; set aside. Add wing pieces to remaining oil mixture; toss to coat. Refrigerate 30 min. to marinate.
REMOVE wings from marinade; discard marinade. Place wings in single layer in parchment-lined sheet pan (or in lined half-sheet pan for trial recipe).
BAKE in 325ºF-convection oven 15 min. Brush both sides of wings with barbecue sauce mixture. Bake an additional 5 min. or until chicken is cooked through. Sprinkle with onions and seeds.
