Wash the potatoes and cook them in boiling salted water with caraway and parsley for about 20 minutes. In the meantime cut off the rind of the toast. Grind the toast finely in a universal chopper. Halve the meat loaf diagonally. Beat the eggs. First turn the slices in flour, then pull through the eggs and the toast crumbs.
Press the breadcrumbs lightly and put the slices aside. Drain the potatoes, rinse and peel. Cut the potatoes into thin slices. Peel onion and chop finely. Heat 3 tablespoons of oil in a pot and sauté the onion in it. Deglaze with stock and vinegar. Season with salt and pepper. Pour the hot vinaigrette over the potatoes and mix gently. Wash the chives, dab dry and cut into fine rolls. Heat the rest of the oil in a large pan and fry the meat cheese slices in it until golden brown, turning them over. Remove and degrease on kitchen paper. If necessary, mix the potato salad again with some stock and season with salt and pepper.
