I save a tremendous amount of money buy NOT buying already ground turkey, chicken, pork and beef. It has also opened me up to more homemade dog food possibilities also as it is difficult to find ground fish, mutton or lamb in a regular grocery store.
Meat grinders come in different shapes and sizes. I use the meat grinder attachment for my Kitchenaid mixer and it works like a champ. You simply attach it to your KitchenAid mixer.
You can also purchase manual, crank meat grinders or electric grinders if you do not have a KitchenAid mixer already.
Once you purchase your food grinder do NOT forget to treat yourself to amazing hamburgers, chicken burgers or meatballs!
