Hobo dinner

Take a half pound of hamburger, and pat into a thick burger. THEN smack down in the middle of a piece of tinfoil. Then you cover it with onions and THINLY sliced potatoes covered with fresh (well uncooked) mushrooms and a "Dollop" of butter.
Cover with another piece of tinfoil and fold all four edges over to form a seal.
Place into a 400 degree oven for about 20-30 minutes, remove and let set for about 5 minutes then you can eat it from the foil or put it on a plate.

Be sure and use plenty of salt and pepper and any other spices you like as if you don't it will come out pretty bland. I guarantee you won't go away hungry!
