Vegetarian ramen is a meat-free version of ramen that is perfect for vegetarians and vegans. The broth is typically made with vegetable stock, miso paste, or soy sauce, and is flavored with a variety of vegetables and spices. The noodles are usually thin and straight, and the toppings can include tofu, mushrooms, bean sprouts, and green onions. Some recipes also call for adding a spoonful of tahini or a drizzle of sesame oil to the broth for extra flavor.
