Grrrrrgh!
Course : Sandwiches
From: HungryMonster.com
Serves: 20
 

Ingredients:

2 pieces rump or sirloin tip roasts
2 cans Campbells beef broth -- or more to cover
1 package dollar rolls
 

Preparation:

The day before a party, bake the roast to medium-rare, or even rare, and save the drippings. Refrigerate overnight. On the day of the party, slice roast very thin, trying to make slices about the diameter of the dollar rolls. Place in a crock pot and cover with the beef broth. This will taste horrible and too salty at first. However, after cooking on low for several hours, the roast will become well done, and tender, and the liquid will be some of the most delicious aus jus gravy ever tasted! Provide tongs to allow for self-serve and make available with the dollar rolls.
