I used the mandolin for everything but the tomatoes. The tomatoes here are so small that they are no match for the eggplants.
I had this for dinner and after an hour in the oven it was not ready but I could not wait another 30 min. for it to be ready. Next time I would bake it longer and brush the eggplant with olive oil before putting it in the oven. I found them to be too dry.
