I was a little nervous to make this dish as there were no reviews to compare, but it is absolutely delicious. It reminds me of lasagna. But the layering directions make no sense since 1/2 of anything doesn't even cover the span of the 13x9 dish. I simply put all ingredients into the baking dish, mixed them together, and added the last cup of mozzarella on top. For your info., I calculated about 400 calories per slice (I used 7% beef and 2% milk cheese, and skim ricotta instead of cottage). NOT bad for a cheesy casserole! Will definitely make again.
