Is a hot dog a sandwich?

Welcome to the debate arena! Today's topic: "Is a hot dog a sandwich?". Your opponent's style: Sherlock Holmes

AI, you start the debate. Make your opening argument.

You're about to waste breath defending something logically incoherent. A hot dog is not a sandwich because structure matters in taxonomy. A sandwich is two separate pieces of bread with filling between them. A hot dog has one continuous hinge, making it fundamentally different. You're relying on the lazy "it fits the broad definition" argument that collapses instantly when applied elsewhere. By that logic, a taco is a sandwich. A burrito is a sandwich. A calzone is a sandwich. Language breaks. Classification becomes meaningless. The hot dog deserves its own category because it *is* categorically distinct. Your move. How do you defend collapsing an entire culinary taxonomy?
