Boil 4 eggs in boiling water for about 10 minutes until hard. Peel 2 onions, dice finely. Mix minced meat, 2 eggs, 4 tablespoons mustard and diced onions. Season with salt and pepper. Drain eggs, quench and peel. Shape mince into a roast (approx. 30 cm long) on the greased fat pan of the oven, placing the boiled eggs in the middle. Bake in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for about 1 hour. Remove the roast and let it cool down for about 30 minutes
In the meantime peel kohlrabi and 1 onion. Cut kohlrabi into slices, onion into fine cubes. Wash chives, shake dry and cut into fine rolls. Put some chives aside for garnishing
Spread the roast with 2 tablespoons of mustard. Spread the potato pancake mixture on top. Bake in the preheated oven at the same temperature for about 10 minutes, then raise the temperature (electric oven: 250 °C/ convection oven: 225 °C/ gas: see manufacturer) and bake for another 10 minutes until golden brown.
Heat butter in a pot. Sauté diced onions until translucent. Dust with flour and sauté while stirring. Deglaze with stock and cream and simmer for about 5 minutes. Season to taste with salt, pepper and nutmeg. Cook kohlrabi in boiling salted water for about 10 minutes. Drain and add to the sauce together with chives
Cut the meatloaf open and arrange on a plate together with creamed kohlrabi. Sprinkle with chives
