In-N-Out Protein Style Cheeseburger
In-N-OutBurgers
In-N-Out's Protein Style Cheeseburger replaces the bun with a lettuce wrap, keeping the patty, American cheese, tomato, spread, and onions. The chain has offered this since 2002 — long before keto and low-carb went mainstream — making it one of the original fast-food bunless options. Nutrition based on standard serving with onion.
