This Philly Cheesesteak is loaded with beef, onions, mushrooms, in a savory sauce, then covered with provolone cheese in a sourdough bread bowl. Just imagine a mixture of Philly cheesesteak and French onion soup and that's what you have here. Yum. Its huge cheesesteak sandwich brought to a whole entire new level, full of flavor. I found this recipe from the cozy apron, made this many times and decided to share with you because I know everyone will love this. Perfect easy meal with easy cleanup, eat right out of the bowl and tear those pieces apart and eat every bite, just dipping it into the stew. As a matter of fact I am making this for dinner tonight.
