Ethical eaters are not necessarily vegetarian. Compassionate meat harvest is possible and requires that we use more than just a few parts and pieces of the animal.
"Offal" is the word used to describe the internal organs of an animal (everything except the muscle and the bone). When I mention organ meats like liver, kidney or heart as the more nutritious option to tenderloin and chops, most people recoil in horror. And yet, a side by side comparison reveals that liver (from a healthy animal only of course) is perhaps one of the most super foods on earth.
