Line a baking sheet with foil because it makes the cleanup a breeze.
Prepare your asparagus by snapping or cutting the ends off. I read somewhere they naturally snap off at just the right spot, but I'm usually a little impatient to do each one individually, so I snap a couple and then use their length as a guide for where to cut the rest.
Wrap your spears of asparagus with the prosciutto. Not every spear needs to be wrapped. In fact, it's nice to have some naked spears so your side dish is more balanced and not every bite is super salty.
Place the wrapped and naked spears on your baking sheet.
Season with salt and pepper to taste (the naked guys are really the only ones that will need a little salt if you'd like),
Place in the oven and broil for about 8 minutes. You'll know they're done when the edges of the prosciutto look a little crispy.
