Preheat grill to 400°F.

In a small bowl, stir together ingredients for the rub.

Add rub to a bowl with the wings and toss to coat evenly.

Add wings to the grill and cook until the skin is crispy and they are cooked through, flipping them every 10 to 15 minutes as they cook. This will take about 30 to 40 minutes. They should register 165˚F internally on a meat thermometer.

In the last 5 minutes of cooking, brush the wings with the sauce.

Remove from grill to a large bowl and toss with remaining sauce. Place on a platter and serve with a garnish of sliced green onion.
