I recommend liver for so many of my clients – it is one of the most nourishing foods you can eat. A great source of vitamin A, folate, choline, and other vitamin B12, as well as protein and some vitamin K2.  Here is one of my favorite recipes; I substitute a natural sauce called ponzu  (http://www.iherb.com/Eden-Foods-Ponzu-Sauce-6-75-fl-oz-200-ml/10824) in place of the teriyaki sauce.  Your whole family may actually like these chicken livers!
