Preheat oven to 400°F. Spray a baking sheet with nonstick spray. Set aside.
In a large bowl, gently mix the ground chicken, egg, breadcrumbs, soy sauce, sesame oil, ginger, and garlic together. Try not to compact the meat as you mix.
Coat your hands with the olive oil and portion out golf ball sized meatballs. Roll the meatballs until they become smooth. This will also coat the outside of the meatballs with oil so they will crisp in the oven. The mixture will be very soft and wet - that’s okay!
2 tablespoons olive oil
Place the meatballs on the prepared baking sheet.
Bake for 15 minutes.
While the meatballs bake, make the sweet and sour glaze.
Once the meatballs register 165°F on an instant read thermometer, brush with the sweet and sour glaze and broil for 2-3 minutes, or until the sauce begins to caramelize.
Garnish with green onion and sesame seeds and serve with additional sweet and sour sauce on the side.

For the Sweet and Sour Glaze:
Whisk the pineapple juice, brown sugar, rice wine vinegar, soy sauce, and ketchup together in a small saucepan set over medium heat. Add a few drops of red food coloring, if desired.
½ cup pineapple juice, ⅓ cup brown sugar, 2 tablespoons rice wine vinegar, 1 tablespoon soy sauce, 1 tablespoon ketchup, red food coloring
Cook until the brown sugar has completely dissolved, about 5 minutes.
Remove 2 tablespoons of sauce and stir it together with the cornstarch. It should form a thick paste.
2 teaspoons cornstarch
Stir the paste back into the sauce and cook for an additional 1-2 minutes, or until the sauce has thickened into a glaze.
Remove the sauce from the heat and set aside until ready to use.
Notes
Storage: Store meatballs in an airtight container in the refrigerator for up to 3 days.
Freezing Instructions: Glazed meatballs can be a little messy to freeze, thaw, and reheat. For best results, freeze unglazed meatballs in an airtight container for up to 2 months. Allow to thaw overnight in the refrigerator and make the glaze prior to serving.
