• 2 small plum tomatoes, seeded and cut into 1/4-inch dice

1. Slice the tuna into 1/2 -inch-thick strips going against the grain.
2. Cut each strip into one inch strips - you should have 24 pieces of tuna.
3. Combine soy sauce and olive paste in a medium mixing bowl.
4. Add the tuna pieces and softly toss to coat.
5. Cover and place in refrigerator to marinate for at least 1 hour or up to 3 hours.
6. In a large thick skillet heat the olive oil.
7. Remove tuna from marinade and pat dry with paper towels.
8. Add 12 of the pieces to the skillet.
9. Sear over high heat until well browned, turning once, about 15 seconds per side.
10. Place cooked tuna on paper towels to drain.
11. Repeat with remaining tuna pieces.
12. Cool to room temperature, cover and refrigerate for at least 2 hours or up to 1 day.
13. Make a chunky olive paste by chopping the olives with 1 tablespoon of the capers.
14. Transfer to a small bowl and mix with mayonnaise.
15. Slice the potatoes into 1/4 inch circles until you have 24 rounds.
16. Put the slices in a bowl of ice water and let sit for 5 minutes.
17. Drain, place in saucepan and bring to a boil over high heat.
18. Lower the heat and boil until tender, 7 to 10 minutes.
19. Remove potatoes from the pot with a slotted spoon and place on a paper towel to drain.

21. Boil over moderately high heat until tender, about 1 minute.
22. Drain, rinse with cold water and place on paper towels to drain.
