Excuse my ignorance, but I am unfamiliar with the term. It sounds ethnic. Cajun?
Pierogies are a northern dish. Nearly impossible to find in the south, but I intend to change that...
It’s similar in appearance to a Cornish pasty, but it’s not a pasty. You make a dough, fill it with a mix of mashed potatoes, onions and olives, fold it up, boil and then fry or bake it. Ideal with baked ham or kielbasa.
