The new burger features a grilled grass-fed beef patty seasoned with Angus seasoning, garlic mayo, tomato, grilled onions, Aussie Jack cheese (similar to Monterey Jack cheese), tomato onion relish, bacon, and leaf lettuce on a toasted plain bun.
The new Grass Fed Beef Burger looks to be the chain's first grass-fed beef patty offering anywhere.
