German Recipes?

Cooks:
This Saturday I am attending the second monthly Supper Club party put on by my friends Sam & Jerry. It is a themed potluck-style dinner party. This month's theme is "bring a dish from the REGION you were born". Having been born in Boerne, I plan to bring German food. Now, I haven't had much experience with this type of cuisine - in fact, I had schnitzel for the first time the other month at the Welfare Cafe (a "must" to experience when in the area, by the way).
Do any of you cooks have a suggestion for my potluck contribution?
I have been playing around with the idea of preparing some sort of mini/finger sandwhich made of German bread, meat, grain mustard, kraut, pickles, cheese, etc. I would love to make weiner schnitzel simply so I have an excuse to say "weiner" all night. Or (and most realistically) I may try to make chocolate stout cupcakes.

Thoughts?
Ich liebe weiner vielen.
Dank.
