Krautburgers, Now with REAL TM Krauts. Yummy.
Kraut actually does mean cabbage.
In Evans, Colorado there is a little shop that makes these over by City Park. Schwartz's Krautburger Kitchen is the name of the place, its been run by the family since it opened and they do indeed make the best krautburgers I have had yet. They have a regular krautburger and a hot cheese that is a bit spicy, though just enough to keep things interesting.
I still can't figure out where they keep getting all these krauts to put in them though, curious.
