<P> The Whopper Jr was created, by accident, in 1963 by Luis Arenas - Pérez (aka Luis Arenas), the only Latino in the Burger King Hall of Fame and president and CEO of Burger King in Puerto Rico . Upon the opening of the first Burger King restaurant in Carolina, Puerto Rico, the molds for the (standard) Whopper buns had not yet arrived to Puerto Rico from the United States mainland and thus there were no buns to make and sell the company's flagship Whopper offering . Arenas opted for honoring the advertised opening date but using the much smaller regular hamburger buns locally available . The result was such a success that Burger King adopted it worldwide and called it the Whopper Jr . </P> <P> Competitors such as McDonald's and Wendy's have attempted to create burgers similar to the Whopper, often nicknamed a Whopper Stopper during the development phase . Wendy's created the Big Classic with similar toppings but served on a bulkie roll, while McDonald's has created at least six different versions, including the McDLT, the Arch Deluxe, and the Big N' Tasty . </P> <P> The Whopper is a hamburger, consisting of a flame grilled 4 oz (110 g) beef patty, sesame seed bun, mayonnaise, lettuce, tomato, pickles, ketchup, and sliced onion . Optional ingredients such as American cheese, bacon, mustard, guacamole or jalapeño peppers may be added upon request . Regional and international condiments include BBQ sauce and salsa . Burger King will also add any condiment it sells upon request, as per its long - standing slogan "Have It Your Way". It is available with one, two or three beef patties and in a smaller version called the Whopper Jr, or without meat in a version called the Veggie Whopper . The Australian franchise of Burger King, Hungry Jack's, sells its veggie burger sandwich as the Veggie Whopper . Additionally, Burger King has sold several different promotional varieties throughout the years as limited time offerings (LTO). With the addition of hot dogs to the company's menu in February 2016, Burger King began testing its first major variant called the Whopper Dog in May of the same year across various regions within the United States . The new dog featured a grilled Oscar Mayer hot dog with all of the ingredients featured on the Whopper sandwich . </P> <P> There are localized versions of the Whopper in several of its international operations, such as the teriyaki Whopper in Japan or the LTO Canadian Whopper . Following its entry in India, to accommodate cultural taboos of India related to beef, the chain has eliminated beef Whopper from its menu and instead introduced mutton Whopper, veggie Whopper, and the chicken Whopper . </P>
