Add the garlic in towards the end so it doesn't burn
Add the sausage mixture to your Crockpot
Meanwhile, chop your carrots an celery
Add all ingredients EXCEPT the tortellini, spinach, cream, and salt and pepper to the Crockpot.

Give it a stir occasionally throughout the cook
Season with salt and pepper as needed prior to servingEnjoy!
