Place the ground pork, garlic, onion or shallots, ground pepper and bay leaf in a shallow cooking pan.
Pour the Canola cooking oil over. Because of the leanness of the pork, I dont want the meat to turn dry so the purpose of adding cooking oil is to help it retain its succulence.
Pour in the vinegar and cook over medium-high heat until the vinegar starts to boil.
Stir, breaking up the meat.
Pour in the soy sauce and stir well.
Cover and simmer for about 10 minutes.
Add the sitaw (string beans), stir, cover and simmer for another 10 to 15 minutes or until the(string beans)sitaw is tender.
The water from the sitaw, the natural juices of the pork, the vinegar and the soy sauce are usually enough to cook everything without the dish becoming too dry.
If it looks like either the Sitaw or Pork meat is taking too long to cook, you can add about 1/4 cup of water.When both the pork and the sitaw are tender, transfer them to a serving plate.
Garnish with chopped cilantro and sprinkle with red pepper flakes.
Serve hot with Rice
