Preheat the oven to 375. Take the first piece of asparagus and holding with both hands bend it and break off the bottom portion where it bends. Either do this individually or place that piece alongside your bunch and cut the bottom off all of them at the same time. Place a piece of the prosciutto on a flat service, and lay your asparagus slightly turned on the slice and wrap it with the prosciutto, pressing to adhere. Place the asparagus in a baking dish or a sheet pan in a single layer. Drizzle with the extra virgin olive oil, sprinkle with salt and pepper and place in the oven. Bake until the prosciutto has browned and become crispy, but not burnt. Remove from the oven and drizzle with a little more olive oil and squeeze the juice of one lemon all over your dish. Serve immediately, or at room temperature.
