 In the summertime, it's layers of zucchini, eggplant, potato, all thinly sliced, tomato, garlic, oregano, a lot of onion, usually just quickly cooked in the oven in thin slices, but then layered and simmered altogether or baked altogether into this beautifully rich and herbal casserole. And in the wintertime, I would do the same thing, except I would replace the zucchini with winter squash.
