Crock Pot Low Carb Pizza Casserole is outrageously cheesy and good. It's like a pizza without the crust. And you won't miss the crust one single bit.
Brown ground beef and sausage in a large pan, breaking it apart as it cooks. Drain off fat.
Place pan over medium heat and add the onion, bell pepper, tomatoes, oregano, and garlic. Cook until onion and bell pepper are soft. Season to taste with salt and pepper.
Transfer mixture to a lightly greased crock pot. Add mozzarella cheese and mix it in.
Pour pasta sauce on top of ground beef mixture.
Layer provolone slices on top. Layer on pepperoni slices.
Cover and cook on LOW for 3 hours.
