Sea Bream Crudo with Lemon and Olives

Step 1

Grate tomatoes on a box grater until all the flesh is grated and there is just skin left; discard skin. Transfer tomato pulp to a small bowl and season lightly with kosher salt.

Step 2

Cut lemon half into quarters; remove seeds and white pith in the center. Thinly slice quarters.

Step 3

Place fish on a cutting board. Hold a long knife at a 45° angle and cut fish with the grain into 1/4"-thick slices (use a sharp blade and aim for one long, clean stroke). Cut each slice in half crosswise.

Step 4

Arrange sea bream on chilled plates. Spoon a bit of grated tomato around and scatter lemon pieces over. Top with arugula, olives, and onion. Pour lemon juice over, then drizzle with oil and sprinkle with sea salt.
