When it comes to roasting eggplants for this recipe, you do not need to peel the eggplant before roasting them. Eggplant skins are edible and add a nice texture and flavor- plus, they contain a multitude of vitamins! Just wash it thoroughly in order to remove any dirt or debris that may be present. If you really don't like the peel, you can also peel the eggplant after baking (once it's cool enough to handle, of course!).
