This is a delicious recipe found in many variations throughout the Middle East, specially Jordan, Syria and Lebanon. This dish is seved hot as a main course with rice, salad and pita bread. Please note, this is the vegetarian version, you may use minced meat in place of tomatoes and onions for the stuffing to make it a meat dish and you may add a layer of lamb bones (on top of the tomatoes and then layer the marrows on top of the bones) to flavour the stock but discard them before serving. Edited May 14, 07: I never had a problem with the liquid boiling over. To avoid such a mishap, as had mentioned in the directions, kindly use a large pot or casserole.
