I bought some frozen, cheese flavoured, perogies to-day and cooked them in the microwave, as suggested. It also gave ways of boiling them or oven baking them. They were all righ,t but very very bland. Any suggestions how to make them taste better. Should they be served with sour cream? We used to get them at the Polish Hall on special occassions and they were delicious, but I have no idea how they were done..
