Jumbo Jack Cheeseburger

What is it?

Two slices of American cheese sit over a single beef patty on a sesame seed bun, with shredded lettuce, tomato, pickles, diced onions, ketchup, and mustard rounding out the build. The cheese melts over the hot patty and sits between the meat and toppings, so the structure stays close to the plain version. Compared with Jack in the Box's regular Jumbo Jack, this one adds a dairy layer and a little more heft without changing the rest of the build. It's a permanent menu item, not a limited run, and it follows the same assembly style as the core burger line.
