Dab meat dry, possibly cut a little smaller. Peel and chop onions. Clean the mushrooms, wash if necessary and cut in half depending on size.
Heat the oil in a casserole or roasting pan. Brown the meat in it in 2-3 portions. Season with salt and pepper. Finally, add the diced ham, onions and mushrooms and fry. Season with salt and pepper.
Crumble the pumpernickel and stir in. Stir in 3/4 l water and stock and bring to the boil. Cover and stew for about 1 1/2 hours.
Cut the cucumbers into slices. Add to the goulash with the silver onions about 5 minutes before the end of cooking time. Season to taste with salt and pepper. Serve with sour cream and coarse pepper. Fresh farmhouse bread tastes good with it.
