I love sardines too. I usually buy the Bumble Bee brand in olive oil, and eat them on crackers with mustard. But you all have some interesting ways of eating them that I'll have to try.
When I was a young mother (back in the stone ages), I used to go to a place that sold surplus items from the trucking industry. For instance, I bought a nice stove there for $50, that only had a small dent on one side.
One day I went in, and they had sardines in the same size can that we buy salmon...13-14 oz? I'd never heard of the brand, but they were super cheap, and I thought I'd give them a try. I bought a couple of cans, and they turned out to be the best sardines I've ever had. They were large...5-6" long, packed in olive oil, about 6 to a can, and very tender and delicious. I went back the next day and bought all they had.
