Justaburger

What is it?

Mustard, pickles, and diced onions are the only toppings on this stripped-down burger from Whataburger, served on a four-inch bun with a single beef patty. No lettuce, tomato, or cheese. Compared with other burgers in the chain's lineup, it sits at the simplest end, with fewer toppings and a smaller build overall. Soft bread holds everything together while the mustard brings sharpness and the pickles and onions add briny crunch. It's sold as a basic hamburger option and also works as a familiar kids' menu-style format. Patties are cooked to order on the flat-top, same as the larger burgers.
