If using regular tofu, it will need to be pressed & diced. If using deep-fried, dice it. Then, marinate the tofu for 5 minutes. Remove & reserve the marinade. Trim the mushrooms & quarter the caps. Heat the vegetable oil in a wok over high heat. Fry the tofu until it begins to change colour. Turn over & fry the other side, be careful not to break it. (If using deep-fried tofu, it won't need as long for cooking). Remove tofu & saute garlic. Stir-fry until it begins to brown. Add the mushrooms & stir-fry for 1 to 2 minutes. Add the marinade & stir-fry for a couple of minutes. Return the tofu to the wok with all the seasonings plus quarter c water. Cook for another 5 minutes. Add the green onions, cook 15 seconds & serve hot.
