Grind your meat again. The second grind will be a much smoother mixture, which is what you want with pan sausage.
Place meat into your stand mixer. This might be a two step process depending on bowl size of your mixer.
Mix meat on low speed for 1-5 minutes. This will ensure spices are evenly spread throughout.

Cook up desired amount and freeze the rest.
