place roast beef (of your choice) in crockpot. Salt and pepper the meat. Add 1/2 cup water, 1 pkg onion soup mix, 1 pkg AuJus powder, 1 can beef broth. Cook on low for 8 hours. Strain the juice and save for dipping. Shred your beef and serve on deli rolls with one slice of melted provolone cheese. Don't forget to dip!
