Heart and onions is really good.I stole this from someone else on another forum.
Save the heart and eat it. I personally get squeamish and dont eat organs , but the heat is just strange shaped meat, so I tried it. In a blind taste test my family preferred the heart to backstrap. Due to the odd shapes it is hard to freeze the heat without getting some freezer burn so it is best fresh. Watch a video on how to cut it up so you dont end up mincing the entire thing.
