Preheat the oven to 400°F.
In a large bowl, toss the chicken wings with 1 tablespoon of oil and season with salt and pepper. Arrange the wings on a baking sheet lined with foil. Cook for 30 minutes, then turn on the broiler. Broil for 10-15 additional minutes, until crispy and cooked through.
Meanwhile, in a small saucepan, combine the remaining oil, ginger, and garlic over medium-low heat. Saute until fragrant and soft, about 3 minutes, making sure the mixture does not brown. Off the heat, whisk in the vinegar, siracha, honey and soy sauce.
In a large bowl, toss the chicken wings with the ginger-honey mixture. Sprinkle with the scallions and serve.
