Bake for 45-50 minutes, flipping the chicken halfway through. While the chicken is cooking to a medium bowl add, peanut butter, hot water, fresh cilantro, chopped peanuts, rice wine vinegar, lime juice, tamari sauce (or soy sauce), garlic chili sauce, and fresh ginger. Whisk until the mixture is smooth. If the sauce is not to the consistency you like it, add more hot water 1 tablespoon at a time.
