For asparagus, snap off tough ends of spears where they naturally give when bent. Place spears into 1-inch of boiling water. Cover the pan and cook asparagus for 3 or 4 minutes, until spears are just tender but remain bright green in color, about 3 to 4 minutes.
Drain and cold shock the spears in a colander under cool water. Return cooked asparagus to skillet and coat with lemon juice and a drizzle of extra-virgin olive oil.
Remove bundles of several spears at a time from the pan and wrap with sliced prosciutto. Pile assembled bundles on a serving plate.
