Ive had potato salad w tuna
in Spain , indeed in the Basque country .
and at a school I went to ( boarder ) the Brothers , who ran the school
were of an order that was Basque , as many of them were .
as I lived there for 2 years.
not on the fancy side as it might be these days
but canned tuna in Spain in 1960
was quite different than here , not extra fancy style in a glass jar
big tins , big chunks , olive oil .
if you like P.S.: and can get some reasonably priced
higher end tuna : its a mighty fine dish .
