Crafted with tender slices of seared and slow-cooked prime rib, Firehouse Subs is now offering their new Prime Rib Steak Sub.
This new Firehouse Sub sandwich features a toasty warm sub roll, caramelized onions, ripe tomatoes, fresh lettuce and pieces of real provolone cheese. The new Prime Rib Steak Sub is also given a shot of deli mustard and Firehouse Subs’ classic garlic mayonnaise.
The Prime Rib Steak Sub will only be available at participating Firehouse Subs locations for a limited time.
