To make Kabobs: Trim green parts off scallions, and reserve for another use. Cut white parts into 8 1-inch-long pieces. Cut tofu into 8 squares. Cut zucchini into 8 1-inch-long pieces. Cut pepper into 8 1-inch pieces. Thread vegetables
and "meatballs" onto skewers, beginning and ending with mushrooms to help anchor other ingredients. Arrange skewers in baking dish
, and spoon marinade over top. Turn skewers to coat, making sure that all vegetables are well covered. Set aside 30 minutes, or cover and refrigerate overnight.
