Brown ground sausage over medium heat while breaking into small pieces. Grab crockpot and turn on high. Place tortellini in the bottom, then the cooked sausage, until all ingredients (except mozzarella cheese) in crockpot. Place cream cheese on top so that it doesn’t curdle. Cook for 3-4 hours on high. If you are home stir ingredients all together as many times as possible. Turn crockpot to “warm” or off then take off lid for about 30 minutes to let set up and add the cup of mozzarella cheese. Stir and serve!
