Place a piece of aluminum foil on a baking sheet and grease with cooking spray. Spread chicken wings in a single layer on baking sheet. Season with salt and pepper.
In a bowl, stir together vegetable oil, soy sauce, bbq sauce, honey and garlic. Pour over chicken wings to coat them thoroughly.
Bake for 50 minutes or until fully cooked and sauce has caramelized. Sprinkle with green onions, if desired.
