These sandwiches are so yummy. They are definitely something I make often because my family loves them. Recipe is from Family Circle.

Yum!! We made this for dinner last night. Since there are only 2 of us, we halved the recipe...otherwise, we made it as described. We set it to cook overnight because we're away too long over the course of the day and didn't want it to burn. Woke up to the house smelling FANTASTIC! We put the meat and the juice in the fridge all day and then when we got home, we put the meat in the oven and used the juice and a little bit of water to create a gravy. Then we put the gravy over the meat and made a fantastic sandwich. Next time (and yes, there will DEFINITELY be a next time) I think we're going to add more pepper juice and the peppers themselves to the crockpot to cook because we like spicy. We may also try other users' suggestions to use beef broth instead of water. Thanks for much for sharing.

Made this for the Superbowl and it was really good and everybody loved it. I didn't use all the peppers the recipe called for because I thought it would be overpowering but next time I will. Thanks!!

This was fantastic. I did use beef broth instead of plain water and added some garlic pwd and black pepper. The first time I didn't have any pepperoncini and it still was wonderful. I never would have thought to use salad dressing mix on beef. I actually have never shredded the beef, just cooked the pot roast in the seasonings. Everyone loves the flavors. The au jus is spooned over the beef and potatoes on the plate. Thanks.
