When I lived in Montreal, one of my favorite meals that people often made for us were Pierogi. I'm not sure why they were so popular there but I fell in love. I even found a really good frozen brand that were easy to fry up on my own for a quick meal.
The sad thing is, I don't think I've had them since I've been back in the states. I get cravings for them every once in awhile but then it passes before I think to try making them. As I was considering a new recipe to make for the Idaho Potato Commission, it popped into my head and I new that's what I wanted to create.
