Slow cooked beef piled deep on a crusty roll with ooey gooey cheese and sautéed peppers and onions. This definitely satisfies my rule about sandwiches. The messier, the better. The tender juicy meat socks up all sorts of great flavors from the broth to the seasonings to the pepperoncini and Giardiniera. There are a lot of variations on this approach to making Italian beef in a slow cooker. And I’ve definitely tried a number of them, but this is by far my favorite. Perfect on a cold fall or winter day.

One Great Sandwich
I would not hesitate to use spicier versions of pepperoncini and Giardiniera in this slow cooker Italian beef since I like a little kick. I used nacho cheese sauce instead of sliced provolone cheese because I wanted to up the messy factor (mission accomplished!). If you’re going the sliced cheese route also consider using pepper jack cheese instead of provolone.
