Place the oil in a very large pot and heat on medium. Add the tomato paste, and measure 4 cans of water for each can of paste. Add remaining ingredients. Then add meatballs, pork and liquid from the pork. Bring to a boil and simmer approximately 3 hours. Adjust salt. It isn't in the original recipe, but I also add 1 cup or dry red wine. Serve over Rigatoni or any other pasta.
