1. Preheat oven to 425F (convection) and spray a baking sheet with nonstick spray.
2. In a bowl, mix together all ingredients for the meatballs (ground chicken, minced ginger, minced garlic, sliced scallions, egg yolk, 1 Tbsp soy sauce, salt, pepper, sugar, sesame oil, white wine or sherry). Roll the mixture into 1-inch balls (option to coat your hands in oil when rolling to prevent sticking). Place meatballs on the prepared baking sheet and bake for 12-14 minutes.
3. While meatballs are baking, prepare the sauce. In a separate bowl, mix together the ingredients for the sauce (grated garlic, grated ginger, 2 Tbsp soy sauce, water, honey, cornstarch, white vinegar). Pour the sauce mixture into a large pan over medium-high heat. Whisk continuously until the sauce thickens and becomes glossy, then turn off the heat.
4. Add the cooked meatballs to the pan with the sauce and coat each evenly.
5. Transfer to a serving platter and garnish with white sesame seeds and sliced scallions. Enjoy!
