03Add the remaining oil to the pan. When it is hot, add the butternut squash. Stir-fry until it begins to color, five to eight minutes. Add salt to taste, the ginger and garlic. Stir-fry for about 30 seconds, and add the cabbage. Stir-fry until the squash is tender and the cabbage is crisp-tender, about six minutes, adding about 1/4 cup water to the pan from time to time if the vegetables begin to stick. Return the tofu to the pan.
04Stir the sweet and sour mixture, and add to the vegetables. Stir just for a few seconds until they are glazed. Remove from the heat and serve with grains or noodles.
