This recipe is from the Taste of Home website. The original recipe is large and makes enough for you to have one casserole to eat and one to freeze. I halved the recipe and did not make another to freeze. Just half of the recipe was more then enough for a meal and left overs for everyone. But if you want another casserole, double the ingredients I have listed.
Pizza Pasta Casserole
1 lb ground beef
1/2 of a large onion, chopped
1 jar of spaghetti sauce
8 oz of spiral pasta, cooked and drained
2 cups shredded mozzarella cheese. ( I probably used a little less)
4 oz sliced pepperoni
