Preheat the grill for direct grilling at about 500°F.
Cut the cantaloupe into cubes, roughly 1-1/2 inches in size. Slice the prosciutto into strips about 1 inch wide. Wrap one piece of cantaloupe at a time with one slice of prosciutto, and slide it onto the skewer so that the skewer holds the prosciutto in place.
Continue this process until you have completed 6 skewers. Grill over direct heat for a couple of minutes on each of the four sides, until the cantaloupe is nicely marked and the edges of the prosciutto are crisped. Serve warm.
Note: Speck is a version of prosciutto that is smoked in addition to being salt cured. For this recipe I used Speck La Quercia Americano, made in Norwalk, Iowa. The apple wood smoke flavor added nicely to the dish, and the Speck was quite a bit leaner than traditional prosciutto.
