YUMMY! This casserole was GREAT! It reminded me of one of my best friend's growing up - her family would get together and make pierogis (I always got stuck rolling out the dough). This had the same flavor with none of the hassel. I followed as directed except I halved the recipe, added some green onion to the onion mixture (it had to be used), and put some cheese on top to bake. Made for Photo Tag.
