I think use chineee roast pork & watercress or kai lan vegetables will taste delicious also. No need so hassle. Just buy available in wet market ready made sambal belacan chilli paste with calamansi (glass can bottle), add mince shallots, garlic & lemongrass. Dish add big onions. Seasoning: sugar, oyster sauce, light soy sauce, Thai style (dash of Thai fish sauce) or maggi soy sauce
