Firehouse Subs offers prime rib on the menu for a limited time with the arrival of the new Prime Rib Steak Sub.
The Prime Rib Steak Sub features seared and slow-cooked prime rib, topped with melted provolone cheese, caramelized onions, lettuce, tomato, garlic mayo, and deli mustard, all on a toasted sub roll and served with pickle spear on the side for a suggested starting price of $6.99.
You can also get a medium sandwich on gluten-free bread for $12.48 (price may vary with location). Just be aware that other items offered at Firehouse Subs restaurants contain gluten, so they cannot guarantee an entirely gluten-free experience.
It’s my understanding that the Prim Rib Steak Sub will start rolling out at participating locations nationwide starting on Monday, October 17, 2022, but Rewards members can get exclusive early access to the new sandwich via the app through Sunday, October 16, 2022.
