Boil the jacket potatoes and drain them.
Bring the fresh smoked sea bream to a temperature of 50°C for about 10 minutes.
Meanwhile, sauté the diced onion in a frying pan with olive oil, add the prepared and roughly chopped vegetables and, at the last minute, clean the tomato pieces, season with salt, pepper and coriander to taste.
Arrange the still hot jacket potatoes and vegetables on a plate. Finally, place half of each gilthead in the middle of the plate and a little butter on the boiled potatoes. Bon appetit!.
