Rub pan with olive oil or spray with olive oil spray. Roll asparagus spears along pan to pick up light touch of oil.
Wrap each spear in a piece of prosciutto (I used 1/3 piece per spear). Don't worry if it isn't tight or shreds some--prosciutto will shrink tighter with cooking
Bake at 425F until spears are al dente and prosciutto is sizzling, about 15 minutes.
Serve warm or cold.
