In a medium bowl, whisk together the soy sauce, rice vinegar, orange juice, pineapple juice, garlic, brown sugar, onion, ginger, and red pepper flakes until combined. Reserve 1 cup for basting later.
Place the chicken wings into a large bowl or freezer bag and pour the remaining sauce over the chicken wings and place in the refrigerator for at least 2 hours or overnight for optimal flavor.
Heat a grill on medium high heat, place the chicken wings over direct heat and cook for 3-5 minutes, flip and grill another 3-5 minutes. Then remove the wings to indirect heat cover and cook 15-20 minutes or until the chicken reaches 165 degrees.
Brush the remaining marinade over the chicken wings during the last 5 minutes of cooking.
Remove from the grill and baste them one more time and season with salt if needed. Serve with any extra sauce!
Notes
I use drummies and flats but you can certainly use the whole wing if you prefer. Chicken thighs would also be great.Baking Directions: Preheat the oven to 425 degrees. Line a baking sheet with aluminum foil, place the wings on the baking sheet and bake for 25 minutes. Flip and bake for another 25 minutes. or until the internal temperature reached 165 degrees. Brush with some of the marinade and turn the oven to broil for the last 2-5 minutes to get some char if desired.
