In This Recipe
Fry onions in ¼ cup of oil on medium heat until soft, translucent and slightly browned, about 20 minutes. Remove onions and add the rest of the oil to the same pan.
Season tuna with salt and pepper and lightly brown on both sides leaving the center rare. Return onions to pan, mix with tuna, increase heat and add the vinegar. Cover and let steam for 3 minutes. Oil, vinegar and liquid from the tuna will create a light sauce.
Place tuna and onions in a serving dish and sprinkle with the mint. This dish can be served hot but it's better cold.
