Heat the oil in a large skillet and sauté the onions for 2 to 3 minutes. Add the carrots and sweet corn. With your hands crumble the tofu on top of the vegetables. Sprinkle the shoyu or ume plum vinegar over the tofu, cover and reduce the flame to medium-low. Cook for 5 minutes or until the tofu fluffs up like scrambled eggs. Remove the cover, turn the flame to high, mix in the red pepper, scallions, black pepper and turmeric. Cook another 2 to 3 minutes, stirring frequently until all liquid from the tofu evaporates. Serve hot for breakfast, lunch or dinner.
