Here is my roast pork with provolone from Tony Luke's at Citizens Bank Park, 9/15/09 (please note I do not eat "greens" on roast pork. It's just my preference). Please excuse the cellphone picture:
The cheese is not melted and the bread is not toasted. This is a traditional roast pork without greens.
And here is my DELICIOUS (I thought it better than the above) same sandwich at DiNic's in Reading Terminal Market, 7/3/09:
Again, cheese not melted and bread not toasted. And of course, sharp provolone.
For those who don't understand about the traditions and makings of this sandwich, please visit my hometown, Philadelphia, Pennsylvania, partake of the real thing, talk to some people, and understand why you CAN'T change it.
