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.

Elementary, my dear friend. You wish to debate whether a hot dog is a sandwich? How delightfully absurd. A hot dog is categorically *not* a sandwich, and the distinction is rather obvious to anyone with a modicum of sense. A sandwich requires two separate pieces of bread with filling between them. A hot dog bun is a single, unified structure—hinged and continuous. The moment you slice bread in two, you've created a sandwich. Leave it whole, and you have something entirely different. This isn't philosophy; it's structural reality. The culinary world agrees. No restaurant serves "hot dog sandwiches." No menu conflates them. Language itself rebels against your premise. Now then, what's your counterargument?
