Fleischkäse is a meatloaf with a really fine texture. You could compare it to maybe the texture of bologna or a frankfurter only the flavor is much different. This is popular in many parts of Germany as well as in Austria mostly as a breakfast and lunch meal. It is cut hot right out of the oven and enjoyed with any variety of mustard. For breakfast it is thinly sliced. In Bavaria a thumbs width slice is served on a roll and eaten much like a hamburger.
