Slovenian hotdog

Here is a picture of a hotdog we had in Slovenia. It was interesting watching them make it. First they take your BIG hot dog bun (which is not cut or anything) and they push it down on this heated spike to make a hotdog sized hole...they let it sit there for a few seconds. Then they put on the mustard or whatever you want. They just spread a glob across the top of the hole in the bread and then they shove a hotdog down into it which then makes the mustard go all the way down into the bun. Ingenious! Anyway, the hotdog was good but it was a really squishy kind, almost as if it was over cooked or pre digested....LOL.
