2 pounds skin-on, boneless chicken thighs
1 cup thinly sliced red onion
2 tablespoons minced garlic
2 tablespoons minced peeled ginger
1/4 cup soy sauce
1/4 cup fresh tangerine or orange juice
Freshly ground pepper
Vegetable oil, for the grill
Combine the chicken, onion, garlic, ginger, soy sauce, juice and 1 teaspoon pepper in a large resealable plastic bag.
Seal and shake to coat the chicken with the marinade. Refrigerate 1 hour or overnight.
Preheat a grill to medium high and oil the grate.
Grill the chicken skin-side down until marked, 5 to 6 minutes. Flip and continue to grill until cooked through, about 5 more minutes.
Let rest 5 minutes before serving.
