1Preheat the grill to medium-high.
2Snap the tough ends of the asparagus off where they naturally break. (This isn't necessary when using Edgar Farms asparagus, as they harvest theirs by hand.) Cut the Queso Fresco into 1/4-1/3" thick slices and place one piece up against each asparagus stalk; wrap a single (or half) slice of prosciutto around it to hold it on.
3Grill for 3-4 minutes, turning as necessary, until the asparagus is charred, the prosciutto is crisp on the edges and shrinks tighter around the cheese and asparagus, and the cheese is oozing a bit out each end.
4 Serve immediately.
