Easy - for beginners
This is so simple and good. Serve it sliced thinly, topped with onions on hard rolls with melted mozzerella or provalone cheese. Serve au jus on the side for dipping. Yum!
Place onion slices in bottom of crockpot, place roast, trimmed of excess fat, on top of onions. Mix together remaining ingredients, and pour over roast.
Cook on low 10-12 hours.
To serve: Take the roast out and slice it thinly. Remove the onions with a slotted spoon and set aside. Pour some of the leftover Au jus into individual serving cups. Toast rolls if desired. Place a couple slices of cheese on the roll. Pile high with hot slices of roast and some of the reserved onion. Top with remaining half of roll. Dip the sandwiches in the Au jus sauce.
