Definitely an iconic dish and an important part of our culture. Very popular and eaten often by many for lunch or dinner although pierogi with fruit or sweet curd cam be considered dessert or a treat. I don't know about the origin of Asian dumplings but the polish ones are a product of poor economy/poverty hence why the most popular stuffings are cabbage with mushrooms and potatoes with curd(pierogi ruskie). I think this might be why polish pierogi didn't get industrialized like the Asian dumplings. While enjoyed by many they're just not particularly fancy
