@Chriza Burger King is about to become the biggest restaurant seller of hot dogs in the country. The fast food chain is broadening its beef kingdom to include two different kinds of grilled hot dogs permanently hitting the menu at its roughly 7,100 U.S. locations later this month. The launch has Burger King poised to steal a sizable bite of a market dominated by convenience stores, wholesale clubs and retailers like Home Depot. With the addition of a classic grilled dog and a chili cheese dog, Burger King is also expanding its menu to include one of America's favorite processed meats at a time when the fast food industry has been scrambling to find ways to appeal to more health-conscious customers with additions such as kale salad and sides of fruit. Burger King partnered with Oscar Mayer to create a proprietary 100% beef hot dog, which will stand apart from most options consumers have because it is "flame grilled" in the restaurant instead of boiled or put on a "roller," the cooking method often seen in convenience stores. The classic hot dog will sell for $1.99 and the chili cheese dog for $2.29.
