About the Dirty The One Pounder Burger
The Dirty The One Pounder combines four flame-grilled 100% beef patties with four slices of cheddar cheese, pickles, and onions. The special garlic mayo sauce, made with garlic paste, garlic powder, and a hint of black pepper, is generously layered twice, making every bite juicy and flavorful. To make eating easier, customers can request a “half-cut” at the register, which splits the burger in half for convenient handling.
