Step 1

Bring a large pot of water to a boil. Add the pasta and cook until almost al dente, but not quite, about 6 or 7 minutes. Drain and set aside.

Step 2

While the pasta boils, cook the Italian sausage and ground beef in a large skillet over medium-high heat until browned and cooked through, about 8 minutes.

Step 3

Layer the pepperoni slices between a couple paper towels. Place the towels on a plate and microwave for 15 seconds to help remove the excess grease from the pepperoni.

Step 4

In a large bowl mix together the pasta, Italian sausage, pepperoni, ground beef, onion, pizza sauce, Italian seasoning, and garlic.

Step 5

Coat the inside of a 5-quart slow cooker with non-stick spray

Step 6

Layer the pasta in the slow cooker, alternating layers with the shredded mozzarella cheese. There should be three layers, ending with the cheese on top.

Step 7

Cover and cook on LOW for 3 1/2 to 4 hours.

Step 8

Serve warm with garlic bread and a salad.
