鳳梨苦瓜湯 Pineapple and bitter melon soup

This dish was inspired by a very popular Taiwanese dish "chicken soup with pineapple and bitter melon 鳳梨苦瓜雞湯".　　I think the soup without the chicken tastes as delicious as with the chicken, if not more.

Ingredients:

1. Pineapple, cut into chunks, 1 cup
2. Bitter melon, cut into chunks, 1 cup
3. Miso, 2 tablespoons
   
4. Water, 4 cups
   

Directions:

1. Put all ingredients in a pot;
2. Bring the mixture to a boil;
3. Turn down the heat and simmer for 10 to 15 minutes.
