Not Your Grandma's Chopped Chicken Liver
Substitute olive oil for butter at will.
Vermouth or pomegranate juice can be substituted for the bourbon. If you prefer non-spirited savory chopped livers, try substituting with stock. It's great while still warm, but better after chilled in the refrigerator.
I like mine medium-rare, but you can cook the livers to your liking.
