Another fantastic Gary Rhodes recipe. Light and delicious! Perfect for a starter course but fantastic for a summer lunch as well. I have made this several times when cherry tomato season comes around. I have also frozen this with great results. NOTE: A basic passata is a sauce made of tomatoes, basil, water, preservative, however some types have more herbs and spices in them, so make sure you like what is in your passata as it will be a main flavour in your soup. You can substitute tomato sauce (not ketchup!) or canned tomatoes (put through the food processor). Sometimes I don’t have passata on hand so I put a can of chopped tomatoes in the food processor (enough to equal the recipe equivalent) and add a bit of basil to it to taste. I don't add water because the canned tomatoes are already in liquid. I hope you enjoy this soup as much as I do.
