Update: This offer has changed to free fries with purchase.

The Jumbo Jack comes with a 100% beef patty topped with two slices of American cheese, lettuce, tomato, pickles, chopped onions, real mayonnaise, and ketchup on a Buttery Bakery Bun. BUT, to make your burger keto-friendly, order yours with NO bun and NO ketchup, and then add extra lettuce (for the “bun”), and extra mayo. YUM!
