My Bubby used a grinder for her liver. First she broiled it in the kashering pan, then she sauteed lots and lots of onion and put it through the grinder together with a hardboiled egg. Seasoned to taste, and voila. I have NEVER made this myself, nor do I ever plan to. You can get pre-broiled/kashered liver. Steer liver tastes better to me than chicken livers. There is a commercial chopped liver on the market that tastes great.
