In a large bowl, mix all the meatball ingredients together and form into meatballs.
In a small bowl, mix the sauce ingredients.
Heat 1 tbsp Lee Kum Kee Pure Sesame Oil in a frying pan over medium-high heat. Add the meatballs and cook until they're cooked through and browned.
Pour the sauce all over the meatballs and continue to cook until the sauce has thickened. Ensure to stir through the meatballs so they have a good coating of sauce on them.
Serve the meatballs on bao buns with the salad vegetables and mayonnaise, sweet chilli sauce and fresh chilli if you like.
