The only prep work is to brown your sausage, whichever kind you choose.
This kind of chicken sausage, although fully cooked, just needs to be browned for extra flavor.

1 (19oz) bag of frozen cheese tortellini
1 small bag of fresh spinach (I used almost all of a 9 oz bag)
2 (14.5 oz) cans of Italian style diced tomatoes, drained
1 block (8 oz) of cream cheese or Neufchatel (I used the Neufchatel for lower fat)
1 lb. of chicken/turkey sausage – pick your favorite
4 cups of chicken broth

Brown the sausage and put all ingredients in crockpot.
Cut the cream cheese into small chunks.
Cook on low for 4-6 hrs.

Serves 4-6

*Keep an eye on your tortellini, it may be done sooner.
*If still soupy, leave lid off for the last half hour or so of cooking.
*For a vegetarian version, omit sausage and use vegetable broth instead.
