Although I may have the reputation as someone who only eats chips (French Fries), the food I most eat is Tuna. And I love it. I usually just buy the most expensive tins. (When I am out at restaurant I like it grilled of course -- which I like the best, but I am not good enough cook to do that at home.) Tuna is best as part of Sushi.
But I find I am a bad person because I eat a lot of Tuna. I do occasionally eat sardines, but I don't really enjoy them. Perhaps now I will bloody Mary my sardines after reading the article.
