Perogies are a dumpling-like Norweigan treat. A dough/pasta crust is stuffed (usually with mashed potatoes +/- cheese or bacon or cottage cheese), and then boiled. Some people pan fry afterwards, to make them crunchy. Apparently, some people deep fry them. Often served with sour cream +/- bacon bits or fried onions. My family sometimes has applesauce with them, but I'm told we're unique in this.
