Buy large wings, otherwise they burn, blacken and end up dry.
2 tablespoons Dijon mustard
2 tablespoons soy sauce
1 teaspoon garlic
2 tablespoon barbecue sauce, store-bought or homemade
2 tablespoons vegetable oil
2 pounds chicken wings, split into two
Combine mustard, soy, garlic and barbecue sauce. Stir in oil. Spread over wings and marinate for 30 minutes.
Heat grill to medium-low and turn off one of the barbecue elements.
Place wings on the side that is turned off and grill slowly, about 15 minutes a side, or until crispy and juices are clear.
