By definition, a hamburger or cheeseburger is a sandwich. Read below. While a Hot dog also fits this description, the
National Hot dog and Sausage Council officially ruled a distinction between the two.
A hamburger (also called a beef burger, hamburger sandwich, burger or hamburg) is a
sandwich consisting of one or more cooked patties of ground meat, usually beef, placed inside a sliced bun - Wikipedia
“Limiting the hot dog’s significance by saying it’s ‘just a sandwich’ category is like calling the Dalai Lama ‘just a guy.’" - NHDSC President and ‘Queen of Wien’
