Fatburger, the hub for 100 percent lean beef burgers, is now offering the Thousand Island Fatburger for a limited time, available until May 20.

The new burger takes taste buds on a flavorful journey to accompany a menu that boasts an array of burger and topping combinations.

The Thousand Island Fatburger adds a new taste profile to the already expansive Fatburger menu, taking a sauce and integrating it directly with the burger.

Starting with 100 percent lean beef, the burger touts a hearty spread of rich, creamy Thousand Island dressing along with the popular “works” toppings: crisp lettuce, juicy tomato, pickles, and onions.

Fans are encouraged to further customize their burgers with an assortment of additional topping options offered, including egg, cheese, bacon, chili, mushrooms, jalapenos, yellow peppers, grilled onions, and guacamole.

“The Thousand Island Fatburger pairs great with any of our hand-scooped shakes for a refreshing springtime experience,” says CEO of Fatburger Andy Wiederhorn. “We’re always looking for ways to broaden our menu and are excited to offer this zesty burger to our dedicated fan base.”
