Think of this as the protein-packed version of the bottom of a Greek salad, where all the dressing gets super concentrated, the vegetables are nicely marinated, and everything is fresh and juicy and good. For a quick summer lunch that's savory, punchy and filling, this hits the spot every time.
Dice the tomato, finely chop 1/4 cup of dill and 2 sprigs of mint leaves (remove the stems), thinly slice 1/4 of a white onion and 1/4 cup of kalamata olives. Add all of this to a large bowl.
Drizzle in 2 tablespoons of red wine vinegar and 2 tablespoons of extra virgin olive oil. Season with 1/2 teaspoon each of salt, sugar, and black pepper. Mix to combine.
Let all of this mingle together while you boil 2 eggs for 7 minutes. Shock them in an ice bath, then peel and quarter them. Add them to the bowl. Drain the tuna and add it in as well. Give it all a good mix.
Serve with big pieces of crusty toasted bread to soak up all the juices.
