This was superyummy! I will definitely be making this over & over. Only thing I did differently was not mix the potatoes & dumplings together (I sliced my potatoes in rounds). So I did one layer of potatoes, top with half onions & cheese, dumplings on top of that, rest of the onions & cheese and then finishing with a layer of potatoes again on top. Sprinkled with a bit of cheese and then I put it in the oven for about 30 minutes.
I really enjoyed this recipe. My DD cleaned her plate she even ate the onions. DH liked it to.
