psobwick:
I am moving forward with the pierogi plan.
When I first read your plan about making chicken pierogi I thought it would be yucky.
But I do remember my Dad <who was a Polish Chef> make a filling of chicken with mushrooms and fried onions in pancakes. So why not do something similar with pierogi ? I think that may work a lot better than putting chicken with cheese ? As cheese is a bit heavy and you have to remember the dough is pretty heavy as well, so the filling needs to be fairly light ? Ditch the smoked version of the chicken <use roast chicken> and ditch the cheese and use the cream with the mushrooms and that then sounds a mighty tasty pierogi !
If you want something smoked in it, then use some Polish smoked ham to give a little bit more taste.
Lot's of Luck !
