Peel, wash and cut the carrot into pieces and cook in salted water for eight minutes. Heat the oil in a frying pan. Sauté the sauerkraut in it. Add stock and cook the sauerkraut for five minutes.
Pour the carrot onto a sieve, drain and add to the sauerkraut. Add fried onions, season with pepper and marjoram. Put everything into an ovenproof dish. Place the salmon ham on top and sprinkle with cheese.
Bake in a preheated oven (electric oven: 200 °C/ convection oven: 175 °C/ gas: level 3) for eight to ten minutes. Garnish with chives.
