**Notes: if using regular soy sauce and not low sodium soy sauce, use 1/2 cup soy sauce and 1/4 cup chicken stock. Regular soy sauce is much much more salty that low sodium.
**Gluten-Free Notes: To make these meatballs gluten free, use gluten free bread crumbs and use gluten free soy sauce. Gluten free soy sauce is as salty as regular soy sauce, so use 1/2 cup GF soy sauce and 1/4 cup chicken stock.
