Story Behind this Recipe
An easy and delicious recipe.
Mix in the tomatoes just before serving so there is no extra moisture. If you are going to eat it a while after mixing it in, remove the seed from the tomatoes. If you replace the basil with shiso leaves, it becomes a Japanese-style dish. If you use parsley or celery leaves, it makes the flavour strong.
