Spray a 6 quart or larger slow cooker with non-stick cooking spray.
Lay the Pork Loins into the crock (I squished them in real good), lightly salt and pepper.
Pour the Stove Top Stuffing on the Pork Loins.
Place the Onions on top of the Stove Top Stuffing.
Then carefully pour the Cream of Celery Soup over the onions/stuffing. I then added a bit more salt and pepper. I carefully added the water, and then topped it by sprinkling the Paprika.
