If you don't have oyster sauce, you can use 2 tablespoons of soy sauce instead.
Purchase chicken drummettes (you'll need about 40) instead of chicken wings. Drummettes are cut up and ready for marinating.
You can prepare and grill these zesty wings up to 24 hours ahead. Place in a rectangular pan, cover with foil and refrigerate. To reheat, place the covered pan in the oven at 350°F for 20 to 25 minutes or until heated.
