The Spicy Cajun Chicken Sub features Cajun-seasoned grilled chicken breast with melted pepper jack cheese, housemade Cajun mayo, lettuce, onions – and now bold jalapeños for an added kick of heat – all served on a toasted sub roll.
The sandwich comes in small, medium, and large sizes for $5.59, $6.99, and $11.59, respectively, though prices may vary depending on where you are.
You can find the Spicy Cajun Chicken Sub at participating Firehouse Subs locations nationwide for a limited time.
