Crockpot pizza is a throw it all together meal. I don't really have a recipe, but here is how I made it today.
pizza sauce( I used 3 cans and I jar of spaghetti sauce)
rotini (I used Ronzoni Garden delight ) I used 2 boxes
pepperoni (I used turkey pepperoni - less greasy) I slice it into strips
sliced mushrooms (fresh or canned)
2 -3 lbs ground beef browned with 1 onion (drained)
shredded cheese (I used a Mexican shredded cheese)
I layer it in my crock pot, sauce, rotini, hamburger, pepperoni, mushrooms, sauce, some cheese and keep going ending with sauce and cheese. I did not cook the rotini first.
I started it on high, but should have kept it on low the whole time. The pasta cooked fine. There are many ways to make this, many use egg noodles , just google it. But this is the one my family likes. It was a hit with my oldest son's football team for their team meals. 3-4 moms would bring a crock pot full - they were all a little different, but the boys ate them all.
