Wings... No matter how many you cook it's never enough! My two go tos are
Asian sticky wings:
Marinate for about 6 hours in a mix of sake, brown sugar, soy sauce, grated ginger, sliced hot red pepper, green onion, and sesame oil. You want the marinade fairly sweet and with enough brown sugar to make a nice glaze. Depending on taste preference you can use more or less hot pepper or ginger. I also like to boil the marinade and brush a couple times. Cook indirect and sprinkle finished wings with toasted sesame seeds and sliced green onion if you want. The sugar on these can burn so they usually stay indirect the entire time.
Tequila lime dry wings:
Put wings in a bag with a shot or two of tequila, a few squeeze of lime, a little oil, lots of salt, pepper, cumin, cayenne, garlic powder, onion powder, chili powder, and paprika. Toss to coat, and leave for 6 hours or so. These can be cooked indirect or direct since there is no sugar to burn.
Both of these also make for great chicken legs too, which are another great tailgate food.
