A simple yet humble recipe courtesy of my mother in law. Heck, I didn't know what to call this recipe! ;) We use store bought Cheemo brand frozen perogie from Canada for this dish, but you can certainly use your own homemade perogie. (I hope one day to learn how to make them and spell the word correctly.) Sometimes I add a potato to the mix to "stretch" the meal even though perogies already contain potatoes. The Cheemo brand has a cheddar cheese/potato variety we really like and an herb/roasted garlic one, too. I noticed the Cheemo site has a similar recipe to this one. Check it out! Serve with a tossed green salad that contains beets, in keeping with the Ukrainian/Russian/Eastern European theme. A Recipezaar member is going to have to set me straight on the correct spelling of pierogies/perogie/-both singular and plural forms.
