Combine water with salt, ground black pepper, oregano, basil, onion salt, parsley, garlic powder, bay leaf, and salad dressing mix in a saucepan. Stir well, and bring to a boil. (You can also simply toss it in the microwave and heat for a few minutes). Place roast in slow cooker, and pour salad dressing mixture over the meat. Cover, and cook on Low for 10 to 12 hours, or on High for 4 to 5 hours. If cooking on low, at the 8 hour mark, use two forks to shred the meat, and then let it continue the rest of the cooking time (if cooking on high, do at about 1/2 hour left); this allows the flavors to really soak into the meat. When done, remove bay leaf.

This is outstanding served on toasted hoagie rolls; just put your desired amount of the meat on the rolls, and top with your favorite sliced cheese (provolone is outstanding) and broil to melt the cheese.
