Cut into the schnitzel several times on the edge, carefully knock out thinly, lightly salt. Whisk eggs and add a little salt. Turn the meat in flour, dip in egg. Then turn in breadcrumbs and press the breadcrumbs on firmly. Heat plenty of butter in a copper pan (alternatively another pan) and bake the schnitzel in it until golden yellow, repeatedly pouring the hot fat over the schnitzel with a metal spoon and draining on kitchen paper. Skip the fat bacon and set aside. Make mayonnaise or use ready-made mayonnaise. Cut the jacket potatoes into slices. Grate the onions and dice the cucumber. Boil the egg and dice. Mix a salad from all the ingredients. Season to taste with salt, pepper and lemon juice and let it steep.
