Lay’s Chalet Sauce potato chips are returning for a limited time in participating Swiss Chalet restaurants. The companies have partnered in 2016 to bring the novelty snack flavor to market for the first time.

The secret recipe sauce of Swiss Chalet has been a staple with Canadian families since 1954, developing a cult-like following, the company said. It was this love of the sauce that inspired Lay’s and Swiss Chalet to create the most Canadian chip ever.

“Partnering with Lay’s was a natural extension for our brand. We pride ourselves on being Canadian, from our 62-year history, to our product quality story and heritage, and our friendly ‘home away from home’ service. This uniquely Canadian potato chip was the perfect way to bring two iconic Canadian flavors to the masses in a new and exciting way,” said Lindsay Robinson, director of marketing, Swiss Chalet.

The potato chips are available only inside restaurants, at participating Swiss Chalet locations, while quantities last. The potato chips can be purchased in 220g family-size bags for CAD3.99 per bag.
