Years ago when I was expecting my 5th or 6th child we had gone to Christmas in the Park in San Jose and I had one of the best Philly cheese sandwiches. Well needless to say I have never had one that good again even when we took a trip to PA.
So I decided to make my own but it had to be easy and fast since my life is so busy and crazy. So I decided to just add a little oil to a large pan, slice up onions and cook them a little until golden on one side, then to slice up green bell peppers and cook them with the onions. Well now for my meat, I just go to the deli and get sliced roast beef and slice it into large strips and throw them in with the peppers and onions. After that is all done I throw mozzarella cheese on top and that is all to it. I add it on a roll and dinner is ready. I added pepper jack to this one and did not really like it all that much.
