The uniform heat of a panini press gives these vegetable sandwiches just the right crispness. But they can easily be made without a press: Heat the panini in a heavy skillet (preferably cast iron) over medium heat, and set another heavy skillet on top of them as they cook.
If you're making a big spread and want to cook the entire pork roast just for the sandwiches, the recipe yields enough pork for 4 baguettes, or 16 pieces. You can also use any leftover pork to make sandwiches as well.
