3 1/2 - 5 pound beef roast (whatever's on sale this week)
2 small jars or one large jar of beef gravy
1 can sliced mushrooms (small or large can depending on your preference)
1 envelope onion soup mix
1/2 cup pre-made Italian dressing
Mix everything up, pour it over the roast, and cook (covered) at 300 degress for 4-5 hours depending on the size of the roast.
Delicious, and melt-in-your-mouth tender.
