Add the soy sauce to the cubed lean parts of the pork and set aside.
In a large pan (I used a wok), place the fatty parts of the meat (cubed) and add 2 Tablespoons of water. Season with a pinch of salt and pepper. Cook on medium-high heat until liquid has evaporated and fat is starting to render.
Add the chopped onion followed by the garlic. Saute until garlic is lightly browned. Add in the lean meat and bay leaves. Cook on medium-high while stirring until the pork juices have evaporated and you see the oil starting to come out. Add chopped tomatoes, tomato paste, 1 tablespoon fish sauce, ground black pepper (to taste) and 1 cup of water. Bring to a boil then lower the heat. Simmer until meat is tender, about 30-40 minutes.
Put the cubed potatoes and carrots and cover . Cook until the potatoes are tender. Add the raisins and bell peppers and cook for 2 more minutes. Adjust seasoning.
Serve with steamed rice or some like it with Pandesal
