Put the stew ingredients in a Dutch oven or ovenproof pot and add 1 cup of water. Toss as much as possible to combine. Once the vegetables soften, it would be easier.
Put the pot over high heat and bring to a boil. Lower the heat to medium, cover the pot partially and cook for 20 minutes, stirring here and there.
Preheat the oven to 400°F/200°C.
Cover the pot and transfer it to the oven. Cook for 20 minutes, or until the eggplants are tender and melting. Taste and adjust seasoning if necessary.
Serve in deep plates. Garnish generously with parsley and a tablespoon of tahini sauce or yogurt, with bread on the side.
