These are very good. I used left over roast from Sunday dinner, shred it and put it in with the Au Jus. I then saute the onions and peppers and put them in with the meat right before I am ready to serve. I made the rolls from a french bread recipe I found on another blog.
Easy Philly Steak Sandwiches
1 boneless beef roast (rump, sirloin tip roast, chuck, etc.) anywhere from 2 to 4 lbs
1 green pepper, sliced
1 red bell pepper, sliced
1 medium onion, sliced
1 McCormick Au Jus sauce packet
In crockpot, dissolve Au jus packet in 3 cups of cold water then add the roast. Cook on low for 6-8 hours or high for 4-5 hours (I cooked mine about 8 hours on low before adding the peppers and onion for another hour) One hour before you plan to eat, shred the beef then slice the peppers and onions and add to crockpot. When it is finished, remove meat and veggies with a slotted spoon. Place mozzarella slices on buns and put under low broil until cheese is melted and lightly browned. Fill the rolls with the meat and veggies, then divide the Au Jus sauce into smaller bowls for dipping.
