To make this a freezer meal, place all ingredients in a resealable gallon-sized freezer bag. Mix together and zip bag closed.
When ready to eat, remove from freezer and thaw in fridge for 24 hours. Spray slow cooker with non-stick cooking spray. Pour contents of bag inside the slow cooker.
Cook on low for 3-4 hours or on high 1 1/2 to 2 1/2 hours, or just until chicken is cooked through.
