Cut the fish fillet into 8 pieces and season with salt and pepper. Heat the fish stock in a saucepan and let the pieces of fish simmer for about 8 minutes at a low temperature.
Add the tomato to the cabbage. Fry the bacon in a pan until crispy. Arrange the cabbage on plates and place the fish fillets on top. Tie each slice of bacon together with chives and place on the pieces of fish.
Tip: The fish should be eaten hot. To prevent it from cooling down too quickly, the plates should be preheated in the oven.
