I make something similar but I put a layer of fat free Greek yoghurt or ricotta in there. The yoghurt is tangy and honestly better than the ricotta but it's about what I have on hand.
That's what this dish was the first time I made it. My wife had to take off in a hurry to fly across the country and the kids and I were unprepared. We stopped at the grocery store on the way home and bought some nice, Italian sausage made by the butcher in the store. When we got home this is what I came up with. We had peppers, onions, cheese, and home made tomato sauce and a new family favorite was born. If you add ricotta you're getting close to lasagna. Not that that's a bad thing.
