Cold soups are perfect to serve before lunch on hot summer days. They tingle awake the taste buds in a more pleasant way, without having to suffer sweaty foreheads! When it comes to cold soups, this low-cal Spanish soup Gazpacho is one of the best choices. A nice crunchy soup with cucumber and capsicum, it is a great source of fibre, vitamin A and folic acid. Keep it chilled and serve it immediately after adding the crunchy mixed vegetable topping.
