The McDouble is a popular McDonald's burger that includes a bun, two beef patties, American cheese, pickles, onions, and ketchup. It is a sort of hamburger made entirely of beef. It was initially introduced in 1997 by the renowned fast-food company. The first of these burgers lacked cheese. They didn't add cheese to the burger until much later. People love cheese, and it was probably so frequently requested as an extra that they decided to just put it on the burger so people would want it more. We also value convenience, and many consumers prefer to order it with cheese already on the burger rather than remembering to request it as an additional. In any case, they please both the business and the client, so it's a win-win situation. The McDouble is said to be a little dry compared to other burgers, although many chain restaurants tout it as one of the most affordable and nutritional burgers. This sandwich has over 390 calories.
