Mushroom Soup "Zupa Grzybowa"
Put the dried mushrooms in a bowl and cover them with boiling water, let them soak for at least half hour.
In a large pot filled with water put all your vegetables and beef and salt pepper to taste. Cook until water boils and turn heat to low.
At the very end I take out the meat with the bone (it usually falls off the bone any way) cut the meat in to small pieces and throw it back in to the soup.
