Mix together the ground pork with the eggs, grated zucchini, soy sauce, garlic, ginger, salt, and pepper.
Portion out and roll into meatballs and cook over medium-high in a skillet until they reach 165° or bake in the oven at 375 degrees until the internal tempo 165° is reached.
Prepare sauce by whisking the ingredients into the chicken stock/broth then heat it in a saucepan over medium-high heat until it comes to a boil.
Cover the meatballs in sauce, by rolling them in the saucepan or using a brush to apply sauce. The sauce is thin, it will glaze the meatballs, and you'll have some for dipping into. If you want the sauce thicker add a tablespoon more cornstarch when making it. The sauce thickens as it sets up, if serving immediately I sometimes make it thicker.
