Am I the only one not repulsed by that? If you get rigt down to it, all the hot dog loaf is is a poorly-executed forcemeat preperation, like a terrine or a galantine. The only real difference is that you would usually use better ingredients for a terrine, not ground beef and hotdogs. They look much better, of course, but that doesn't mean you couldn't make the "hot dog laof" look better with a little help.
At any rate, I'll bet it tasted great.
