Noodle toppings are a popular way to add flavor and texture to noodles. Common toppings include HATS, which is an acronym for herbs, aromatics, spices, and vegetables. These toppings can be used to enhance the flavor of noodles, as well as provide additional nutrition. Popular herbs used as noodle toppings include basil, oregano, and parsley, while aromatics such as garlic and onion are also commonly used. Spices like chili powder, cumin, and turmeric can add a kick of flavor, while vegetables like mushrooms, bell peppers, and carrots can provide a crunchy texture.
