I read the packaging and it says that one can add meat into it. There are two packages inside and one is sufficient for a small pot of soup for 2. Use two for stronger flavour and larger portion. So one day I made a chicken herbal soup ala bak kut teh style by adding halved tau fu pok (beancurd puffs), fu chuk (beancurd sticks, the ones for stews and soups), dried shiitake mushrooms (soaked and sliced), a can of button mushrooms I've received during CNY, and fresh enoki mushrooms.
Fairly easy to make, just need to dump in some chicken meat and the soup packages plus the rest of the ingredients except for button and enoki mushrooms which I added towards the end. Since I was using kampung chicken, I boiled it for about 1 hour or so on low heat.
This pot of soup is good as one pot meal to go with rice, easy peasy and less cleaning up for a complete meal. Well, can chuck in some greens at the end to really make it complete :p
I've seen this soup package at vegetarian supply shops and mini markets, not sure if can be found at supermarkets or hypermarkets. Will update if I do.
