Peel kohlrabi and cut into thin slices. Blanch in boiling salted water for about 5 minutes. Drain and let drain. Wash cutlets, dab dry, cut into pieces. Heat oil in a coated pan.
Fry the meat for 2-3 minutes while turning, season with salt and pepper and remove.
Wash the tomatoes, possibly halve them. Wash the chives and cut into small rolls. Spread the kohlrabi, meat and tomatoes in an ovenproof dish (approx. 24 x 30 cm; 2 l capacity).
Whisk sour cream with eggs and chives (up to 1 tbsp). Season with salt, pepper and nutmeg. Pour over vegetables and meat. In a preheated oven (electric cooker: 175 °C/circulating air: 150 °C/gas: see
manufacturer) bake for about 35 minutes until the egg icing has set. Sprinkle with the rest of the chives and arrange everything.
