1. Preheat the panini maker or, if you don't own one, place a cast iron skillet in the oven and preheat oven to 350 degrees Fahrenheit.
2. Slice the ciabatta rolls in half horizontally and scoop some of the bread out of the top half to hollow out. Drizzle the bottom half of each roll with olive oil.
3. On each bottom piece of bread, pile half the arugula and top with half the mint.



4. Lay two slices of prosciutto on the arugula, followed by the mango and the mozzarella, dividing equally between the two pieces of bread. To close each sandwich, cover with top half of ciabatta .



5. Place sandwiches in panini maker for about 5 minutes, until cheese is fully melted. Or, if you don't have a panini maker, arrange sandwiches side-by-side on a baking sheet and cover with cast-iron skillet. Cook for about 5 minutes, until cheese is fully melted.
