I like beef liver. Maybe once ot twice a year for something different. I flour it and cook it in bacon grease. Like my mother used to do. Served with mashed potatoes with a lot of butter.
I never did the liver and onions thing. I wasn't a big cooked onion eater as a kid.
And it might be nutrient dense, but just remember it's a filter. Just like kidneys. Those organ meats are best eaten in moderation. As tasty as they might be
