Teriyaki tofu and vegetable skewers are a great option for vegetarians and vegans. Cut firm tofu into cubes and marinate them in a homemade teriyaki sauce made with soy sauce, ginger, garlic, and brown sugar. Thread the tofu cubes onto skewers along with your favorite vegetables like bell peppers, onions, and mushrooms. Grill the skewers until the tofu is golden brown and the vegetables are tender. Serve these flavorful skewers with steamed rice or noodles for a complete meal.
