French Dip Sandwiches (Crock pot)

My cousin, Laura, shared this recipe with me and my family loves it.  I love it because it's tasty and so easy!

1 Big Boneless Roast (I usually use a beef rump roast)
1 cup soy sauce
4 c. water
2 bay leaves
2 t. rosemary
2 t. thyme
2 t. garlic powder
1 package of sliced french rolls or hoagie rolls (Any firm roll will work.  You don't want the roll too soft or it will be too soggy.)

Put all ingredients except rolls in crock pot.  Cook on low 8 - 10 hours.

Remove roast and cut into very thin slices or shred.   Place beef on rolls and dip sandwiches in the au-jus from crockpot.
