Wash and trim the asparagus. Boil in hot salted water for about 10 minutes, drain and dunk them in cold water for a few seconds. Bunch the asparagus in groups of three or four, and wrap each bunch in a slice of Franchi Prosciutto. Arrange the bunches on an oven tray, drizzle with olive oil and season to taste. Bake at 180° degrees for about ten minutes, serve warm.
