Native Pittsburgh foods to cook at home?
I am in a cooking club that meets monthly, and every month there is a theme. We are supposed to follow the theme, but it's usually very broad and we get to interpret it our own way. For example, "Reds on the Beach" resulted in everything from a Cuban arroz con pollo (because they are Communists and have beaches) to grilled shrimp to fruit soups (because you could pack them for a beach picnic, and they were based on strawberries or watermelon) to overturned nubs of cheesecake (the bottom resembling sand) with raspberries pinned to the top with a paper drink umbrella. I was traveling for work unexpectedly so my plan for tomato tart (already did one this season and had many requests when I posted pix on my blog and FB) was bagged in favour of "octodogs" because I could swing by the grocery on my way back to town and I remember eating them on the beach as a kid.
Next month's theme is "Pirates". I'm tempted to make something from Pittsburgh because I am a sports nut. I could wimp out and obtain local brews, but I'm more of a cook than a drinker. I did some looking-up and most of the suggestions don't scream "Pittsburgh" to me: Halušky and Kielbasa, Pierogis, Klondike Bars. I did see reference to deli sandwiches with coleslaw and fries inside, but I don't know if I will be able to make fries at the home we're at next month. I also saw references to "city chicken" which might be an option.
Then I thought I'd ask the greater SE-scape if y'all have any suggestions. My quick search found passing (or maybe passing-over) references to food in Pittsburgh, but someone has to have substantive information for me! I used to go to Pittsburgh annually but we mostly picked up food at the grocery store to cook where we were camping. A friend was at a convention there last year and sent back a review of a brewpub, but that's not much help for cooking. Does anybody know which sandwich won to become the signature sandwich for 2011 at PNC Park? Any other suggestions? Recipes?

It was in a barbeque shack an hour or so out of Dallas, where you lined up at the smokers with a plate and paid by the pound. Ditto for your sides (in the walled part of the building), but the iced tea was free and came out of something that looked like a moonshine still. They had pretty much any kind of meet you liked - chicken, pork, several kinds of beef, and the random game that came their way.
