This pizza casserole is quick and easy, and actually healthy. Though it doesn't look that way. And that's intentional. We hide all the healthy pizza topping ingredients under the pepperoni so you feel like you're eating a naughty dinner, when in fact you are having a veggie packed dinner that's just 265 calories!Special Tip: If you want to boost protein more, cook 4 Italian sausages and dice. Then add them to the filling to boost the protein.
