Hamburgers are a popular type of sandwich consisting of a cooked patty, usually made from beef, placed inside a sliced bun. They are often garnished with various toppings such as lettuce, tomato, onion, and condiments like ketchup and mustard. Hamburgers are enjoyed worldwide and are a staple in many fast-food restaurants. The origins of the hamburger can be traced back to the late 19th century in the United States, although its name is derived from the city of Hamburg in Germany. Over the years, hamburgers have evolved into numerous variations, including cheeseburgers, veggie burgers, and gourmet options, making them a versatile and beloved meal choice.
