What the heck is a Lincoln log sandwich?

It was in the Sopranos. Carmella made some kind of sandwich I had never seen before and she called it a Lincoln log sandwich. It looked like a hot dog or some kind of sausage, split in half with either cream cheese or sour cream on it. I have never heard of this before. I tried looking up lincoln log sandwich and log sandwich, nothing came up. Anyone have an idea of what this is?
