Perogies are basically dumplings with filling - most cultures of the world have something similar (asian dumplings, Italian tortellini, etc.).
Most commonly, the filling is potatoes and cheese - but there are many others which can be used as well.
You make a dough, cut in circles, put a bit of the filling on the centre, pinch closed, then boil them til tender. Usually served with sour cream and onions sauteed in butter, but also good with fried bacon bits, lol!
They are also good when fried after being boiled.
To give you an idea of how to make them
