Add onion slices to slow cooker and lay chops on top of onion
Sprinkle chops with the soup mix and just 3 tbsps of the gravy powder (reserve the other 3 for the end of the recipe)
Add vegetables
Cook on low for 8hrs
Mix the remaining 3tbsp of gravy powder with a little water and add to slow cooker. I then left the lid off for 10 minutes to thicken slightly prior to serving.
