The addition of yogurt sets this baba ghanoush apart and makes it Mangia's. As anyone who loves eggplant knows, this is a wonderful dip for wedges of pita or for vegetables. It is also very successful served as an accompaniment to lamb or chicken. We roast the eggplants over the gas burner on the stove top. If you'd rather not do that, you can roast them in the oven. We prefer the charred flavor that only comes when you use the open flame.
