This is a great way to eat really fresh seabass. Try cut the fish a thin as you can because if it is too thick it becomes a bit unpalatable. The addition of the tomatoes and chilli helps cut the richness of the raw fish. Try and avoid using lemon juice because the tomatoes have enough acidity and adding lemon would kill the delicious subtle flavour of the seabass.
