Lukewarm salad with smoked herring

Boil the carrots in a large pan with water and salt in 8 minutes until al dente. In the meantime, heat the butter in a frying pan and fry the potatoes for 8-10 minutes and season with salt and pepper. Add the leek and cook for another 6 minutes. Add the tomatoes and let yourself be warmed in a stirring way.

Drain the carrots and add to the potatoes. Clean the herring and cut it fine. Put the potato-vegetable mixture in a large bowl and mix in the herring. Pour the dressing over it. Add salt and pepper and cut the parsley above it. Divide the salad over 4 plates and serve immediately.
