Add chicken stock, potatoes, canned tomatoes, cabbage, turnips, carrots, a medium onion, garlic and a smoked ham hock to the pot. Oh, and a clean, round stone!
Bring to a boil and then reduce the heat to low. Cook the soup until thick and the vegetables are fork-tender. This takes about 2 hours. After the soup cooks, remove the meat from the ham hock and add the meat back to the soup. Season with salt and pepper and serve.
