This is a hearty soup that's excellent to eat by itself or with rice. Mongo beans are also called mung or green beans. Malungay leaves are very nutritious and the tree is sometimes called a horseradish tree.
In a medium pot, boil the mongo beans in water for 40 minutes until soft. Mash the beans.
In a large pot, saute the onion and garlic in olive oil. Add the diced pork, and salt and pepper to taste. Cook for 3 minutes.
Add the prawns, mix and cook for 2 minutes. Add the diced tomato and cook for 3 minutes.
Add the chicken broth and simmer for 5 minutes.
Add the mashed mongo beans, mix well, cook for another 5 minutes, stirring occasionally to prevent the mixture from sticking to the bottom of pot. Add more chicken broth or water if the mixture is too thick.
Add the malungay leaves. Cook 2 more minutes and serve hot.
