Season with Oregano, Parsley, Cajun Seasoning, Cayenne Pepper and Thyme. Play with it as you like I always like to add a little extra spice to really bring out the flavors.
Give everything a good stir to mix.
Cover and cook for 7-8 hours on Low or 3-4 hours on High.
With about 30-45 minutes left in cooking time Add thawed Shrimp.
