I love chicken hearts and gizzards. The livers were OK, but not my favourite. The gizzards and hearts are.
I used to buy them and cook them up for suppers when the kids were young. Boiled, of course - sprinkled with salt - YUMMY!
Same with turkey gizzards and hearts.
Sardines are great too, especially the jalapeno and tomato sauce sardines. Billionaire sardines are the best of the olive oil sardines.
No dogs any more - so I get it all!
