From my old CrockPot Blog-
When I was looking for a recipe like this, I found several and I have just combined them into this one that works for us.
Crockpot Pizza - feeds 6
1 lb hamburger, browned and well drained
8oz shredded mozarella
1/4 c chopped onion
1/2 package sliced pepperoni - chopped
half a package of rotini (spiral) pasta
1/2 can cream of mushroom soup (substitute)4 oz mushrooms
1 jars pizza sauce
Brown hamburger with onion. Mix hamburger, onion, pepperoni, cream of mushroom soup, mushrooms and pizza sauce together in Crockpot. Cook on low for 4 hours.
Just before you are ready to serve, cook pasta. Add the pasta and shredded cheese to the sauce mixture in crockpot and cook together until the cheese in melted - about 15 minutes.
