"bife de atum" and a possible calderetta

I like fish more than beef, and it's not breaking news for those who know me. Today for the lunch I ate what the Portuguese call "bife de atum", basically a tuna steak that even resembles a beef steak at a first sight, garnished with corn, carrot, chopped potato, black eyed peas, onion and some spices. Catched some random small fish today, a good amount of small fish that may end up in a calderetta. Not so much liver oil could be extracted today.
