If you love steakhouse flavors but want something you can enjoy on the go, the Steakhouse Beef Sandwich is a winner. It’s loaded with thin slices of tender, seasoned steak that are grilled until juicy and full of flavor. The beef has that deep, rich taste you expect from a good steak, and it’s made even better with toppings that bring balance and texture.

The sautéed mushrooms add an earthy depth, while the caramelized onions bring a mild sweetness that works perfectly with the savory meat. Melted provolone cheese gives each bite a creamy, mild richness, and the steakhouse aioli adds a tangy, garlicky kick with just the right amount of herbs. Everything comes together inside a warm, toasted ciabatta roll that’s soft inside, slightly crisp outside, and sturdy enough to hold all that goodness without falling apart.
