This turned out really well and wasn't time consuming to put together. I used the sausage and couldn't find shredded italian cheese mix, so it was all mozzerella and parmessan cheeses. I think the flavor would just improve with getting more cheese mix in there. I did the 4 layers in my pan and it would probably be a 12 servings not 16. This is actually a good base recipe to start personalizing with more vegies which is what I'll try next time. Definitely a keeper.
