I went to college in Tucson, Arizona and loved this little spot named Greasy Tony's. My friends and I would go there after the bars closed for amazing spicy philly cheesesteaks. I moved back to Michigan, and haven't been able to find a replacement since. Here is my adaptation. These are great sandwiches to have when the weather starts to turn cool. I also make a horseradish sauce to put on top but they taste great without the sauce! These make heaping sandwiches. When my market is out of hoagie rolls, I have used hot dog buns, hamburger buns and onion rolls. If you like it spicy, add more pepperoncini. Also, red pepper can be used in lieu of green pepper.
