Fresh new potatoes, cut into wedges, can be used instead of the refrigerated potatoes. Because the refrigerated potatoes are partially cooked, microwave the fresh ones for 4 to 6 minutes before adding them to the packets.
Make these packets up to 24 hours in advance. Pop them on the grill when you are ready to eat.
Although these hearty packets can be a complete meal, a crisp mixed-greens salad would be a nice addition.
