Preparation Slice zucchini into paper-thin rounds either in a food processor fitted with a 1-mm. blade or with a mandoline or other hand-held slicing device. Arrange zucchini rounds in one layer, overlapping them slightly, on a large (about 8 by 12-inch) platter and sprinkle with arugula. Drizzle oil and vinegar over zucchini and season with salt and pepper. With a vegetable peeler shave curls of Parmesan on top.
