Weigh out all the protein chicken wings, chicken breast, chicken hearts and beef liver.
Put the chicken wings in the freezer to lightly freeze in preparation for going through the meat grinder and any of the other meat that you will grind.
Grind the chicken wings in a meat grinder (I like to double grind) I prefer to grind all the meat. You can however choose to finely chop the other meat components.
Grind the chicken wings and other meat.
