I made Reuben sandwiches with the leftovers from my corned beef. Chris and I absolutely loved these sandwiches. We had them with leftover cabbage and potatoes on the side, but could barely eat any of the veggies because the sandwiches were so filling!! I almost hate to say it because the corned beef and cabbage was so good, but these may have been even better!
In order to make Reubens you need stone ground mustard, thousand island dressing, swiss cheese (I used reduced fat), sauerkraut, rye bread, and corned beef. The horseradish is optional, Chris and I ended up deciding against it and just going the traditional Reuben route.
