Cut squash diagonally into 1/2-inch thick slices. Toss with oil and chile flakes; season to taste with salt and freshly ground black pepper. Arrange in one layer in preheated panini pan. Close press; cook 3 minutes or until squash is seared and tender.
Slice off the tops of the ciabatta rolls; save for another use. The rolls should now be 1-inch thick. Split the rolls horizontally. Turn bottom halves up and top with 2 slices cheese, squash mixture, mint and remaining cheese. Close sandwiches with top halves of ciabatta rolls. Brush lightly with additional olive oil, if desired.
Cook sandwiches in preheated panini maker or on gas grill for 4 to 5 minutes, turning once, until cheese is melted and bread is golden brown.
