Tear off enough sheets of foil for each dinner you are making. Place a hamburger patty (or chicken breast) in the center of each foil. Cut onion into rings. Peel and dice potatoes. Peel and chop carrots into sticks. Add onion rings, potato chunks, and carrot sticks to each hamburger patty. Top with salt, pepper, and season-all salt. Seal up each foil dinner individually. Place on a cookie sheet. Bake at 350 for about 1 hour. Also, great in the coals of your campfire…just be sure to turn it regularly!
