Crockpot Philly Cheesesteak

2 lbs thinly sliced roast beef deli meat, or fajita meat. I have used frozen steakum, broken into strips
1 can beef broth
1 onion sliced
1 green pepper, sliced
1/2 red pepper, sliced, optional
8 oz. fresh mushrooms, sliced
1 clove garlic
8 hoagie rolls, I used soft, presliced brioche baguettes (found in bakery area--less bread), cut in half
8 slices thin provolone cheese

Place liner in crockpot. Place beef in bottom. Add onion, peppers, mushrooms, & garlic. Pour broth over top. Cook on low 4 hours. Stir occasionally. Serve over rolls and top with cheese. Rolls may be toasted if desired. YUM!
