I have had some incredible steak and cheese sandwiches in Philadelphia over the years. There is just something about thin sliced steak, melty cheese, grilled onions, and fresh bread that makes it one of the best comfort foods ever. The problem is I cannot hop on a plane to Philly every single day when I get the craving, so I started making this lighter version at home.
For this recipe I used steak tenderloin because it has to be one of the best cuts of beef out there. I mean, if Gordon Ramsay uses tenderloin for his famous Beef Wellington, then you already know it is going to be tender and packed with flavor. Thin sliced tenderloin cooks quickly, stays juicy, and works perfectly in a homemade steak and cheese sub.
This sandwich still gives you that classic steak and cheese flavor, but with lean steak tenderloin, controlled portions of Cheese Whiz, and a lighter spicy mayo sauce that keeps the calories much lower while still tasting incredible.
