This is a good way to win over someone who isn't a huge sauerkraut fan. Also good with ground turkey! Add a bit of thousand island dressing on the top and use corned beef leftovers from St. Pat's Day for a Reuben-style taste!
I use this recipe at work,(in a bakery). So, it makes a lot! Good for institutional use or when a large amount is needed; and ample room is available. Wait till the banana's are almost rotten for the best taste. They'll be gross but tasty. Slowly save them up in your freezer till you have enough; or check with your grocery store for overripe ones.
