Chicken livers
The only thing I know about chicken livers are....well, that they should STAY with the chicken??? Haha! I'm teasin' you Loretta. My daddy loves the things as well. Acccckk!! I expect if you can puree them they'd be great. I know they have a lot of iron and are supposed to be good for ya! It's probably gonna be a matter of just tryin' it once to see. I expect the craving you have is coming from that "memory in your brain" about how wonderful they were at a point in your life. ;) Sometimes when you have one of your fav foods for the first time, it's not the same....sometimes, it takes a while for things to be "as good" as they once were.
I personally LOVED chick-fil-a nuggets, but now....I don't know, even if I take off the breading, they just don't do it for me, ya know? I still love chicken and tolerate it well, but just not as crazy about the nuggets as I was prior to surgery.
