Arrange an oven rack 6 inches below the broiler. Preheat broiler to high.
Brush the tips of the asparagus with the olive oil, and sprinkle very lightly with a pinch of salt.
Take one piece of prosciutto and wrap it around 3 spears of asparagus. Repeat with the remaining asparagus and prosciutto.
Place on a sheet pan. Broil for 2–3 minutes, or until the prosciutto is starting to brown.
Flip and broil for another 2–3 minutes until prosciutto is crisp and browned on the edges. Serve immediately.
Notes
You can find thinly sliced prosciutto at the deli counter—ask for it to be sliced thinly. I find that the packaged prosciutto is sliced too thickly for this recipe.
