Burger King is sliding into the slider game. The fast-food chain announced that it will test a new “King Size Sliders Box” for a limited time.

The company said that the new offering is bigger than a slider but smaller than a burger. Guests can build their own box of six king-size sliders, mixing and matching from their choice of three flavors of burgers.

The Deluxe Slider is topped with fresh lettuce, tomato, pickles and tangy burger aioli.

The Steakhouse Bacon Slider features melty Swiss cheese, crispy bacon, crispy onions and peppercorn sauce. The third option is the Bacon & Cheese Slider, topped with crispy bacon, melted American cheese and tangy burger aioli.

All three of the options have a “100% flame-grilled beef patty” and come on a “soft and buttery slider bun.”

The news comes shortly after Burger King announced that the Whopper is getting a makeover for the first time in nearly a decade.
