First of all, the texture. When pan-fried from frozen according to the package instructions the perogy wrapper gets... puffy. Very sturdy. No give. Like deep fried bread, or tiny pizza pockets. I've had other pan-fried perogies, and dumplings, and none of the wrappers have ever ended up like that before. 

Secondly, the filling. The flavour was nominally bacon and potato, but it had a hard time staying inside its fried dough pouches. Also I'm not convinced there was bacon in there. The filling tasted like they had once LOOKED at a closed bag of crumbled bacon bits, demurely, from the opposite side of the fridge, not making eye contact.
