Preheat your oven to 400 degrees. On a parchment lined baking sheet, place your prosciutto slices in a single layer. Bake for 10 - 12 minutes, until the prosciutto crisps, then remove and set aside.
In a blender, combine the cantaloupe, cucumber, bell pepper, salt, vinegar, and olive oil. Blend very well until extremely smooth. Strain into an air-tight container and allow to chill in the fridge for at least an hour (this can be made the day before serving as well).
When ready to serve, portion the chilled soup evenly into bowls, then garnish with freshly picked basil, a few pieces of the crisped prosciutto, an extra drizzle of olive oil, and a fresh crack of black pepper. Enjoy!
