Place chicken breasts in the bottom of the slow cooker.
Cover the chicken with the Cajun seasoning.
Add the rest of the ingredients EXCEPT the Penne Noodles.
Cook on high.
After about 2.5 hours, check the chicken. If it is cooked, take the chicken out and cut into bite sized chunks and place back into the slow cooker.
Add the Penne noodles at this time.
Once the Penne noodles are fully cooked, it is time to serve!
When serving, top with grated Parmesan cheese.
