Ingredient Spotlight: Ground Pork

Ground pork is made by taking unseasoned pork, usually the shoulder or butt, and grinding it into ground meat. It’s an affordable option and incredibly versatile. Any recipe that is made with ground beef, turkey, or chicken can be made with ground pork. Ground pork is high in protein and thiamine, which you need for a healthy metabolism.
