Nice! I created a "pizza pasta casserole" a couple years ago and its outstanding.
Mine is a crossover. A casserole like lasagna with pizza toppings we like; Italian sausage, pepperoni, onions, mushrooms, black olives, pickled jalapenos and marinara sauce. People have been doing pizza casseroles for a long time, but I had no idea when I created my recipe!
I like to microwave the pepperoni carefully on some paper towels a bit before adding so it doesn't leach out quite as much liquid fat in to the casserole. I messed up last time and just mixed everything together instead of topping the casserole all pretty-like with the pepperoni and jalapenos but it was still delicious.
I made a pizza pasta casserole, a beef stroganoff casserole and a ham mac-N-cheese casserole before the spring became summer heat this year; cut them up in to portions, froze them individually on a sheet pan and vac sealed them and we enjoyed "easy button" meals all summer! Just finished the last of the stroganoff last night and now I'm ready for casserole and stew season again! I smell gumbo coming...
