Vegetable-based sauces are culinary preparations made primarily from vegetables, often blended or cooked down to create a flavorful liquid. Common ingredients include tomatoes, peppers, onions, and garlic, which can be combined with herbs and spices to enhance taste. These sauces can be used in various dishes, from pasta to stir-fries. These sauces are popular for their health benefits, as they are typically low in calories and high in vitamins and minerals. They can serve as a base for many recipes, providing moisture and flavor without the need for heavy creams or oils. Examples include marinara sauce and pesto.
