I decided to try making warm sandwiches for lunch. My first attempt was a hot ham and cheese, and the next day I decided to try a cheese steak. I simply sauteed some onions, mushrooms, and peppers with thin sliced roast beef from the deli. This was finished with some cheese and loaded into a hoagie roll. This was very easy, and beat most of the sub shops in this area. Certainly not Philly worthy, but a great way to spice up a boring sandwich.
