If you want to prepare part of this casserole ahead of time, after draining the beef mixture and stirring in the pizza sauce, pepperoni and olives, cover and refrigerate up to 24 hours. Be sure to heat the mixture to boiling before spooning it into the baking dish and adding the topping.
Pizza cheese blend is a packaged mixture of the favorite cheeses used on pizza. The flavors are perfect for this casserole.
To tote, tightly cover the baking dish with foil and place in an insulated cooler or a box lined with newspapers or towels. Be sure to take along a large serving spoon.
