Many people don't eat soup for lunch as they say it doesn't fill you up. The key is to add some protein. This could either be a sprinkle of nuts or seeds on the top, or some coconut milk swirled through – or in the case of this soup some delicious butterbeans. Despite the fact that this soup has beans it is still light and smooth. With all the winter colds and flu around at the moment this is perfect if you are feeling below par.
