I had a thought. What happens to the chicken skins from the boneless skinless chicken? Are they the famous meat by-products? Well I got my hands of some and used them for some dog treats They are simple to make and dogs love them. A 2 inch square skin will shrink down to a 1 inch square treat a little salt and your dog will love them all natural no preservatives. They are the right side for training treats.
Take chicken skins place on parchment lined baking sheet and and place a second sheet of parchment and a second sheet tray
Bake at 375 for 20 minutes they should be crispy
Coat with a little salt
