For a charcoal or gas grill, place packet on the grill rack over medium heat. Add salami halves, cut sides down, to grill. Cover if using a gas grill. Grill salami for 4–6 minutes or until grill marks appear; remove from grill. Grill potato mixture for 25–30 minutes or until potatoes and beans are tender, turning packet every 8–10 minutes to prevent burning. To check vegetables, use tongs to carefully open the foil packet. If vegetables are not tender, seal packet and return to grill. Remove packet from grill, and cool vegetables about 15 minutes.
