Preheat the oven to 375°F. In a large bowl, mix the turkey, egg, panko crumbs, cornstarch, fish sauce, sriracha, sugar, onion, garlic, mint, cilantro and black pepper. Combine well and roll into 1-1/2-inch balls.
Heat the oil in a large skillet over medium heat. Add the meatballs in a single layer, being careful not to overcrowd the pan. You may need to work in two batches. Brown lightly on both sides and transfer to a foil-lined baking sheet. Bake for 8 to 10 minutes, or until the meatballs are no longer pink in the center.
While the meatballs finish in the oven, combine the peanut butter, coconut milk, sugar, rice wine vinegar, garlic, sriracha, fish sauce and hoisin sauce in a small bowl. Mix well, place in a serving dish and top with ground peanuts.
For serving suggestions, see the recipe introduction or simply serve over steamed jasmine rice.
Tips for Making This Recipe
This peanut sauce is a bit different than the type you generally find served with satays or summer rolls. It is not as sweet or thick. Feel free to adjust the heat according to personal taste.
