Preheat oven to broil on high. 

Cut off the tough ends of the asparagus and rinse with cold water.

Take one piece of prosciutto, fold it in half, then wrap around an asparagus stalk; repeat until all of the prosciutto slices and individual spears of asparagus are used. Place on cookie sheet.

Place under the broiler, one spot below the top in the oven. 

Let broil for 4-5 minutes or until prosciutto is a bit crispy and asparagus are soft, watch carefully to ensure nothing burns (every oven is a bit different). If they aren't done after 5 minutes, continue broiling in 30 second increments until fully cooked (remember the prosciutto doesn't need to be cooked through, it is already edible as-is, but the asparagus needs to be cooked so it isn't too crispy). 

Remove and let cool slightly. Serve and enjoy.
