Preparation
Preheat oven to 400ºF.
Cut the eggplant in half lengthwise and rub the cut sides with EVOO. Place on a baking sheet cut side down and roast until tender, about 30 minutes. Let the eggplant cool until you can comfortably handle them then scoop the flesh out of the skin and into the bowl of a food processor. Pulse until puréed and transfer to a mixing bowl.
Combine eggplant with the onion, garlic, 1 cup breadcrumbs, 1/2 cup Parmigiano-Reggiano, 1 egg, thyme, mint, lemon zest, salt and pepper. If needed, add additional breadcrumbs until mixture is moldable -- you can roll the mixture into balls now, or refrigerate the mixture for 30 minutes to make it easier to work with.
