1) two or more slices of bread or a split roll having a filling in between
2) one slice of bread covered with food
The word hot dog refers either to the sausage that you buy squeezed in a plastic package with 7 or so of its kind, or to the same sausage heated and served in a long split roll.
When it's served in the roll, it's also a sandwich.
We know: the idea that a hot dog is a sandwich is heresy to some of you. But given that the definition of sandwich is "two or more slices of bread or a split roll having a filling in between," there is no sensible way around it. If you want a meatball sandwich on a split roll to be a kind of sandwich, then you have to accept that a hot dog is also a kind of sandwich.
You could hinge your anti-hot-dog-as-sandwich argument on whether the hot dog sausage qualifies as a "filling," but if you choose to interpret filling narrowly as only "a food mixture used to fill pastry or sandwiches," rather than broadly as "something used to fill a cavity, container, or depression," then you're not going to allow any single-item filling to qualify a food item as a sandwich—which means there can be no thing as a peanut butter sandwich or a bologna (or even baloney) sandwich.
Hence, a hot dog is a sandwich.
The dog is between the two pieces of bread. It's meat. It has the sauce and stuff. So... Why shouldn't it be called a sandwich? The definition of sandwich is... "An item of food consisting of two pieces of bread with meat, cheese, or other filling between them, and it's eaten as a light meal."... That was actually taken from a dictionary. The hot dog only has one piece of bread, but it surronds the hot dog as if it was two. The bread has meat, ketchup, mustard, relish, etc. between the two pieces of bread. It is eaten as a light meal. So, therefore, a hot dog is legally a sandwich.
Hot dogs are not sandwiches just like tacos are not. Hot dogs exist in their own class. As do tacos.

Do hot dogs have two pieces of bread? No. Therefore, they are not sandwiches.
While one may think it counts as one, the FDA doesn't classify hot dogs as sandwiches. This is due to the open faced nature of the hot dog. However the FDA does include wraps and burritos as members of the sandwich family, as they are not open faced. In conclusion, Hot Dogs are not sandwiches.
SANDWICH isn't included in the title of HOTDOG plus its a hot food so it cant count as a sandwich. Maybe a toasty or bap or whatever just not a sandwich. Try and think of a hot sandwich........ There isn't one!!! In conclusion, a hot dog is not a sandwich.
