Single beef patty, sesame seed bun, lettuce, tomato, pickles, diced onions, ketchup, and mustard. It's the plainest burger in Jack in the Box's lineup, with no cheese or special sauce, just the standard fast-food build. The patty is cooked on a flat-top, so you get a little browned edge and a soft center. Compared with the Jumbo Jack, Double Jack, and Ultimate Cheeseburger, this one keeps the formula simple and skips the extra patties, cheese, and specialty sauces found on those larger builds.
