7-11 Cheeseburger Bite. Hamburger in the shape of a hot dog, with nacho cheese injected into the middle. Put it on a hot dog bun, and top it with their free chili and nacho cheese. Most 7-11s don’t carry them any more, so when I find one that does, I immediately buy two and them shotgun them in my car in the parking lot.

Also, some dude said that in the northeast US they call them “hamdogs”.
