A hamburger, burger or hamburger sandwich is a popular dish believed to have been invented in the United States owing to influence from the cuisine of Hamburg, Germany. It usually consists of a patty of ground meat placed between the halves of a bread roll, although "hamburger" may refer also to the patty on its own. A hamburger sandwich can be served with tomato, lettuce, onions, condiments and other ingredients sandwiched along with the meat.
In popular culture, the character most associated with hamburgers is Popeye's friend J. Wellington Wimpy. While his preference for hamburgers is well noted, this may stem from their convenience and availability, as Wimpy is not one to shy away from any meat-based dish that could feed his massive girth, as long as it can be obtained for free.
