Delicious! We are a family of three and between my husband and son, they both had three slices! This is definitely going on to my make again list of recipes. I substituted cottage cheese for the ricotta and it worked fine. I also substituted 1 Tbsp. parsley seasoning for the fresh parsley and it worked just fine as well. The next thing I did, since none of us are big sausage eaters, was to substitute 1 to 1 1/2 lbs. ground turkey instead. Again, the taste was great! It is all in your taste and what you want to do and use. This recipe didn't seem to be overpowered with tomato or meat, an equal combination of both. So, I don't agree with it tasting like eating spaghetti sauce. As far as making it without the crust? That sounds like a good idea, but instead of layering everything, mixing it all together and serving as a casserole with rolls and sides of choice!
