If you've never roasted an eggplant, you must. The trick to delicious eggplant is to make sure it is thorougly cooked, but without drying it out. The skin is not edible, so peel the entire fruit with a vegetable peeler, then slice the eggplant into 3/4 inch slices. Lightly greese a baking sheet, and bake at 450 or even 475 until browned.
