Hi AJ- I don't usually eat frozen food (except waffles), but I saw them in the frozen food aisle and a friend had them and said they were pretty good, I tried them. They aren't as good (of course) as the homemade ones....(sigh) but they are okay.
Na, A.J., this is meant, mainly, for you two. Mrs. T is the McDonalds of pierogis and the crack of the cocaine world. Eat them if you need a quick fix but the real deal lies within the talented hands of local churches and friends/family whose last names end in the letters "ski" or "ka".
Then again, you could make them yourselves. It's, essentially, potato-stuffed pasta. Have at it and lemmie know how it comes out!
