4-5 lb. beef brisket
1/2 pkg. dry onion soup mix
1 lg. onion, sliced
4-6 potatoes, peeled & cut up
2 (24") pieces heavy duty aluminum foil

Place 2 pieces aluminum foil on top of one another. Place sliced onion on foil in the middle. Put brisket on top of onion slices, fat side up. Sprinkle on soup mixture on top of beef. Surround beef with potatoes. Bring the two ends of foil together, roll and crisp tightly. Fold remaining 2 ends tightly (no juice or steam to leak out). Place in roasting pan. Bake at 350 degrees for 2 hours. Take care when opening foil - steam will escape.
