In-N-Out Burger's secret menu has low-carb gems

Posted by Luis F. Escalante on March 31 in Restaurants

While fast-food chains such as Burger King, Hardee's and Arby's are just now rolling out low-carb sandwiches, customers of In-N-Out Burger have been ordering high-protein, low-carb hamburgers wrapped in lettuce for more than 30 years. The protein-style burger is part of In-N-Out Burger's "secret menu" that has developed over the years as the restaurants strived to accommodate requests for customized food.
