Leftover’s used were sour cream and chive rolls, beef pot roast, and jus made from the pot roast drippings, all made from scratch.

I also thinly sliced a half red onion that was floating around in the fridge and caramelized it, and threw on some muenster cheese for good measure.

After I assembled the sliders, I griddled them on my cast iron skillet and used a second skillet to smoosh them a bit for better contact with the pan. All in all it took about 30 minutes, and most of that time was caramelizing the onions.
