Tomato soup is a soup made from tomatoes. It is commonly used as an ingredient in more complex dishes, and, unlike most savory soups, it may be served either hot or cold. It can be made from chunks of tomato or with only a puree. The canned condensed version of the soup is one of the leading styles in the U.S. and is most associated with the Campbell Soup Company. In the UK, Heinz Tomato Soup is one of the archetypal comfort foods. Many toppings can also be used, such as sour cream, shredded cheese, crackers or salsa.
