Heat 2 tb olive oil in a small skillet and saute the onion until it browns slightly. Than add tomato, salt, pepper, allspice, and parsley. Cook over medium low heat until the mixture breaks down to almost a puree. Drain currents, and add the to the tomato-onion mixture, and cook for 10 more minutes. Stuff the cooked mixture in the slits in the eggplants with your fingers or a knife. Set the eggplants in a flame-proof dish that iwll just hold them. Pour oil over the eggplants until oil level is about halfway up the eggplants. Add garlic & bay leaf to the oil.
