Pour pasta sauce and alfredo sauce into greased slow cooker.
Add one pound of uncooked ziti and 1/2 cup of water.
Top the noodles with mini pepperoni and 1 1/2 cups of shredded cheese.
Mix together the sauces, ziti, pepperoni, water and cheese.
Top with 1 1/2 cups of pizza sauce.
Cover and cook on low for 3-4 hours, until the pasta is tender. Mine was ready in three hours.
If you love saucy pasta, add an additional 1 1/2 cups of pizza sauce and stir it in.
Sprinkle the pizza casserole with more shredded cheese, a little oregano and grated parmesan.
Replace the lid to allow the cheese to melt.
