Peanut butter pie? Must be a regional thing because I don't think that I've ever had it. Pecan pie is big in Texas though. By the way, it wasn't until I got to know some Europeans and visited Europe a couple times that I realized just how American peanut butter is. Last time I went to Europe I actually brought a couple bags of Reese's just to share with some friends haha.

To address the topic, another dish somewhat specific to here would be brisket. Some people from other parts of the country have never even heard of it surprisingly enough.

I'm from korea and our most popular and most served food is probably (kimchi) spicy cabbages with rice. For dessert probably ice cream or cake and coffee.

I'm from Peru and our food is incredibly diverse. I love eating 'ceviche', 'papa a la huancaina', 'anticuchos', 'lomo saltado', etc for desserts we usually eat 'picarones' or 'suspiro'

I live in the Southern part of the USA and some comon foods in my area are country ham (basiclly salty ham) biscuits and gravy, fried chicken, and of course apple pie.  Oh and also peanut butter pie.

I'm from the United States. We eat food from all over, but some very common foods we eat are pizza, lots of chicken and of course hamburgers. For dessert we often eat icecream or some type of cake.
