This hearty steak sandwich is packed with bold flavor. Tender slices of juicy steak are piled high on a crusty baguette, layered with sautéed onions and mushrooms, and slathered with a creamy mayo-mustard sauce. A handful of fresh arugula adds a peppery zing. When shopping for your steak, be sure to choose one labeled 100% grass-fed for the best taste and quality.
