Of all the tomato recipes that are around, tomato soup is one that it is so versatile: it can be served warm in the summer; to be enjoyed outside with a glass of white wine, in the winter it should be enjoyed piping hot with a hunk of bread and a dash of chilli, perhaps. Marcello Tully's tomato soup recipe is gloriously creamy but if you are after a truly healthy lunch you can reduce the cream if you prefer.
