Cheesesteak Sauce and Onions

I had been wanting to get a Philly cheesesteak sauce and onions during our nearly a week long visit to Katie's. I finally got one on the last night before leaving when Katie ordered some cheesesteaks from Lorenzo's Pizza Steaks & Hoagies in Manayunk delivered to her house. She ordered several versions of their steaks and cut them up for everyone to try but for me she got their classic sauce and onions one which I loved.
