4boneless skinless chicken thighs if using breasts, pound the thickest parts flat
Lay out the pieces of foil and oil the centers of each.
In the center of each piece of foil pile the potatoes and onions.
Brush corn cobs with melted butter and place next to the potatoes. Sprinkle everything with your basic spice rub (or spices).
Lay the chicken atop the potatoes and onions and sprinkle with more spice rub.
Seal the edges all nice and tight, but leave a little room for steam. If taking camping, put the pouches in ziplock baggies in case of leakage (which did happen).
Cook right away or freeze to take camping (use in the first 1-2 days).
Cook thawed packets 5 inches from the fire/coals, 15 minutes on one side and 15 minutes on the other. If they are closer because of stationary grate at the campsites, just turn them a little more often and move them to avoid hot spots. In this case, they might cook closer to the 20 minute mark, so you'll have to be checking after 15 minutes.
*It's okay if the packets are still partially frozen when you cook them as they seemed to cook the same amount of time over the hot campsite fire.Make Ahead Tip: You can make the packets a few hours or days ahead, whatever works for your schedule. You can even freeze them in advance and cook partially thawed at the campsite, like mentioned.
