Cut prosciutto slices in half lengthwise. Wrap a half slice around each scallop, securing with a toothpick. If you really want the pork flavour to pop, you can use a whole slice on each scallop. Just fold it in half lengthwise and then wrap the scallop as usual.
Place wrapped scallops on a greased baking sheet (or one lined with parchment paper). Turn your oven to broil and place the top rack on the second level from the top. Once the oven is heated, place the baking sheet on the top rack.
Broil for about 10 minutes, or until scallops are cooked (opaque white). Keep a careful eye on them because over-cooked scallops are rubbery.
