Italian Beef Sandwiches

2 1/2 pounds beef chuck roast
2 (1 ounce) packages dry Italian salad dressing mix
1 cup water
8 oz. pepperoncini peppers (It comes in a 16 oz. jar and I use half. You can use more or less depending on how spicy you want it. 8 oz. is pretty spicy even!)
Hamburger buns or kaiser/deli rolls

Place the roast into a slow cooker and add Italian dressing mix. Pour in the water. Cover, and cook on High for 6 hours. During the last hour, shred the meat with two forks and add the peppers and as much of the juice as you like for additional flavor. If it does not shred easily, cook longer. Reserve liquid to dip sandwich in for extra flavor. Serve on buns and enjoy!
