Dry rub or montreal steak seasoning
Dice up some onions and put about half of them in the bottom of the crockpot. Lay roast on top of it. Pour on 8-10 dashes of Worcestershire sauce. Then coat with a dry rub and garlic. Add more onions on top of the roast. Add ½ cup of water around the edges. Cook in crockpot on low for 8 hours or until meat reaches 170 degrees.
