Some do, some don't, but those that do... do? Break out the gravy and saute some onions, we're having liver! One of my childhood favorites for taste and melt in your mouth texture. Didn't know this then but liver is also the most nutrient dense organ meat, and it is a powerful source of vitamin A. Grease up that pan with some Omega dense lard from our pasture raised pork fat and you my friend are eating well!
