Though we usually make casseroles for a whole week of dinner, we recognize that other kinds of cooks may benefit from our experiences (and the wide variety of casserole combinations we have tested so far). In this recipe we have combined our love for combo pizza and Italian pasta into a single dish for all the pizza/pasta lovers out there. We dedicate this casserole to all families who want a good hearty meal that looks good and tastes good!
