I’ve heard of that before but I’ve never seen anyone make or sell that around here. The pictures I get searching for that mainly look to be thin slices stacked up or on a roll with other stuff and it looks like a breakfast sandwich. Around here, we’d do that with Taylor Ham, or pork roll.

This is the closest pic I could find to what I’m talking about. They refer to it as a Nashville smoked bologna sandwich, and it seems more BBQ style than hot dog style.

We may be getting into semantics, but such is the case when we get into regional specialties. Having the meat slice about the same thickness as a hot dog keeps it having that same hot dog mouth feel you wouldn’t get with a stack of thin slices or if it was smoked, and it would have more traditional hot dog toppings than the sandwich toppings of a bologna sandwich or the BBQ fixings of the smoked bologna sandwich.

I’ve never heard anyone make reference to it specifically as a “flat hot dog” other than by one older guy I worked with 20+ years ago that suggested it to me. But I’ve shared them with other people over the years, and they’ve all found it fun and intriguing as well. At this point, it’s kind of my own personal food of mythical origin, so it’s a fun concept I can mention whenever the subject of unusual hot dogs comes up.
