Place one melon cube at the end of a prosciutto strip. Add 1 small mint leaf (or half a leaf if they’re big) against one side of the melon. Wrap the prosciutto snugly around the melon and mint, letting the ends overlap slightly. Secure with a wooden pick or small skewer right through the center so the prosciutto stays in place.
Repeat with the remaining melon cubes, prosciutto strips, and mint leaves until you have about 16 bites, or as many as your ingredients make. Arrange the bites on your serving platter, tucking in a few extra mint leaves for garnish so it looks bright and springy.
