Spray the Slow Cooker with cooking spray
Combine in a mixing bowl the large cubed potatoes, onions, salt and pepper to taste and 2 Tablespoons of butter melted.
In the slow cooker lay the 4-5 pork chops at the bottom. Place 3 small pats of butter on the chops. Use a 1/3rd of the Italian dressing mix and sprinkle it over the pork chops.
Do another layer of the pork chops with 3 pats of butter and then a 1/3rd of the Italian Dressing Mix sprinkled over it.
Pour the potato/onion cubes over the pork chops and sprinkle the last of the Italian Dressing Mix over the potatoes. Cover and cook on low for 6-7 hours. High for 4 hours.
