An appetizer : Wild Mushroom Sage Pierogi

My wife generally prepares the bulk of the T-Day meal but I prepare the appetizers. For 20 years now, I make these Pierogi to have with wine and drinks. A couple of years ago, I made a different appetizer and our gathering of kids and friends revolted. Although they liked the rustic tart, they missed the pierogi. Can be made ahead of time and frozen.
The dough is from an old Molly Goldberg cookbook; the filling is my own invention.
