Quiznos describes their prime rib as "coated in a dry rub of black pepper, garlic, salt, and paprika then slow roasted for 8 hours." They've offered it a few times over the years on a limited-time basis.
The new 8" Prime Rib Horseradish XL Sandwich features a half-pound of prime rib, Swiss cheese, sauteed onions, and horseradish sauce on your choice of bread.
The new Italian Prime Rib consists of prime rib, provolone, sauteed onions, giardiniera, green peppers, and marinara sauce on your choice of bread.
You can find both prime rib sandwiches at participating locations throughout the fall and winter, while supplies last.
