A chuck roast ( 4-5 lbs.) is perfect for this because it cooks down so tender and shreds easily. The only other things you need are a jar of sliced peperoncini and a couple of packets of dry Italian dressing mix.
So, first cook the roast. I have an electric pressure cooker that I use, but it can be cooked in the oven.
When the roast is tender, let it cool, then shred it up, removing the extra fat and other unpleasant matter.
Pour the broth in a fat separator.
Add the shredded beef back to the pan, sprinkle with 2 packets of the dry Italian salad dressing mix.
Pour in the whole jar of peppers...including the liquid.
Cover and cook a bit longer. About 7 minutes in the pressure cooker or 40 minutes in the oven.
It's good on it's own or on sandwich buns with a slice of Swiss cheese.
It makes a lot but it freezes really well.
See that potato on the right side of the photo? It is Pioneer Woman's "Crash Hot Potatoes" recipe...and it's really good. I use parsley (instead of rosemary) when I make them.

Oh, and I like a mixture of butter and olive oil, rather than all olive oil for the potatoes.
