1 (2 1/2 to 3 lb.) arm roast
1 can cream of mushroom soup
1 pkg. Lipton's onion soup mix, dry

Line baking dish with foil (enough to also cover roast). Place roast in foil lined pan. Add mushroom soup. Sprinkle the onion soup mix over the mushroom soup. Fold ends of foil together to cover the roast. Place in preheated 300 degree oven for 2 1/2 to 3 hours. About 50 minutes per pound.
