I used to love (still do)
'judias blancas'. Some of my other favourite foods were different kinds of salmon dishes, most traditionally with potatoes. We used to eat all kinds of foods at home, since both of my parents like to cook and especially my dad likes to try out different things.
Some foods that I've always liked associated with my "area" (that being mostly entire Finland) are
'hernekeitto',
'karjalanpiirakka',
'makaronilaatikko', and
'limppu'.
