Slice cantaloupe half into 6 wedges, then into approximately 1-1/2" pieces, discarding the rind. Cut prosciutto into approximately 1-1/4" x 3-1/2" strips. Wrap each piece of melon with a strip of prosciutto, securing with a toothpick.
To make the balsamic reduction, heat the balsamic vinegar in a small skillet over medium-high heat. Simmer about 3 to 5 minutes, or until vinegar has thickened and reduced to about 1 tablespoon.
Drizzle serving plate with balsamic glaze and olive oil. Place wrapped melon onto plate and sprinkle with mint and pepper. Serve. Refrigerate any leftovers.
