Scale and clean the sea bass, remove the fillets and the skin (but keep the skin), take out the bones, remove the belly. (Raw, you lose 40–50% of the fish.)
Preheat the oven to 180°C/gas mark 4.
Put the skin on a baking sheet covered with parchment paper, season with salt and pepper, and drizzle with olive oil.
Put another sheet of parchment paper on top for pressure, then bake for around 40 minutes to make chips/crisps for the garnish.
Finely dice the fish fillets into approximately 0.5cm pieces, and set aside in a large bowl.
Wash and quarter the tomato, deseed, and finely dice, then add to the fish.
Peel and thinly slice the shallot and chives. Mix with the fish and tomatoes.
Season with salt and pepper according to taste. Add the olive oil and mix together.
Plate as you wish, be creative, and add a bit of lemon juice to your liking.
