1- 1 beef roast (size is not important)
2- 1 packet of dry Italian or ranch dressing ( I used ranch)
3- 1 C. water ( I added a little more and watched during cooking to make sure it wasn't getting dry)
4- sub rolls
Place all of the above into a crock pot (with the exception of the buns:) and cook on low 8 hours. Shred the meat and place back in the crock pot; ladle meat and juices onto buns.
Now you can always add sliced provolone and giardeniera to it as well; I used just the provolone and it was heavenly with that alone.
