16 oz of Rotini pasta (Please ignore the picture I couldn't decide which past to use, I went with Rotini.)

1 Pound ground beef, cooked and drained

2 cans of pizza sauce

2 Cups of mozzarella cheese

about 20 slices of Pepperoni (I suggest Turkey pepperoni. It's less greasy.)

½ and onion, chopped

Cook your pasta according to the directions. Drain.
Cook the ground beef fully with the chopped onion and drain.
Add the cooked pasta to your crockpot.
Layer the ground beef on top.
Add the sauce.
Add the cheese.
Add the pepperoni.
Cook in the crockpot for four hours on low.
