I don't follow this recipe exactly but it's very easy and delicious. I use frozen veggies mixed with the sauce. It's quick and easy. I also mix my ricotta cheese with some parmesan and mozzarella. I don't like spinach or mushrooms so I leave those out and the extra can of tomatoes because I have a couple of picky children. It's nice to be able to run home over my lunch break, throw this all together and have dinner ready for everyone when we get home. No fuss.
