Spicy Roast Beef Sandwich

Bit of house keeping before we get to the recipe- assuming you didn’t just click “skip to recipe,” in which case, enjoy!

A friend showed me a new Chicago style Italian beef sandwich place in town, but they’re on the other side of the city and don’t deliver to me. So I had to make my own, but a little bit different (for laziness reasons).

Instead of shaved or shredded, it’s chopped. I talked myself out of getting a deli slicer and I was far too impatient to shave the roast by hand.

Instead of giardiniera I just chopped a red pepper and a cauliflower into my standard pickled jalapeno. It worked really well!

And finally, this has chipotle aioli on it.

Because I put that shit on everything
