Combine all ingredients in the slow cooker, except for the shrimp and the rice.
Cook on low for 6 – 7 hours, stirring occasionally
In last hour of cooking, salt the shrimp lightly, and then add them to the crockpot
In the last half hour of cooking, add the rice and stir. Replace cover. You want the rice just to warm through and take on some of the cooking flavors.
