So Vegetarian is almost an unheard of word in the Philippines, but while in college I still wanted the Filipino tastes while trying to be vegetarian. Since all of the recipes I know had meat (even the veggies are cooked in pork) I had to come up with some of my own. This is one of those. Tofu sinigang apparently isn't unheard of in the Philippines but this recipe came out of trial and error. The soup is pretty sour cooked to "full strength" but can make a pretty nice fast meal with rice.
