You make these individually for how ever many people you have eating.
Make out a good sized hamburger steak/patty (uncooked) and place it in
the center of a nice big square of aluminum foil. Season with salt, pepper, and garlic salt. Pile on chunks of potato, baby carrots, and onion chunks. Salt, pepper, and garlic salt everything a little more. Put about a 1/4 to 1/3 can Campbell's Golden Mushroom Soup on top and add a generous chunk of butter or margarine on last. Fold up the aluminum foil so you have an airtight pack. Bake on a cookie sheet in 375-400 degree oven for about 1 hour to 1 hour 15 minutes. You can check for doneness at 1 hour; may take longer if you have more than 4 hobo packs bakin. This goes real goooood with cornbread and butter!!
