Rinse the chicken wings
under cold running water, then drain
and blot dry completely with paper towels. Place the wings in a large bowl and sprinkle with the garlic salt, pepper, cayenne, and oregano. Season just 1 side of the wings for mild, or for hotter wings, turn the wings to coat the other side with seasonings and then cover and marinate in the refrigerator for 24 hours.
Preheat a grill
Grill chicken wings, turning once, until the juices run clear when pierced with a fork. Serve immediately with a side of Blue Cheese Dressing.
