Portillo’s has decided to get into the chicken sandwich game with a little Chicago style.

The new Spicy Chicken Sandwich is served on a toasted brioche bun with tomato, lettuce and the new Hot Giardiniera Sauce. The sauce is also available on the side to bring the heat to more than just the sandwich – it can be used as a dipping sauce for chicken tenders, fries, onion rings and more.

“This is a delicious new addition to our menu,” says Maria Reichl, Portillo’s VP of Culinary Development and Field Operations. “Portillo’s has always prioritized quality, and this sandwich is no different. It’s spicy, crispy and brings our signature Chicago flair with the giardiniera-packed sauce.”

For a limited time, fans can get a bottle of the Hot Giardiniera Sauce to bring home for $5.99 each. You can also head to portillos.com to order the chain’s giardiniera-themed merchandise, including swimsuits and pool floats, as well as pre-order a children’s book written by Portillo’s.
