Ingredient for 4 serving are (1) 2 scallions, cut into chunks (2) 1 (1-inch) piece peeled, fresh ginger, cut into quarters (3) 2 garlic cloves, put through a garlic press (4) 1 pound tuna steak (5) 2 teaspoons reduced-sodium soy sauce (6) 2 teaspoons toasted sesame oil (7) 6 cups mixed salad greens (8) 1 cucumber, thinly sliced (9) 1 carrot, shredded on the large holes of a box grater (10) 2 tablespoons plus 2 teaspoons balsamic vinegar
1. Place the scallions and ginger on a cutting board and chop almost to a paste by rocking the blade of a chef's knife back and forth, rotating it slowly. Keeping working in this manner until the mixture is very finely chopped. Alternatively, place scallions and ginger in a small food processor and pulse until very finely chopped. Place the scallion mixture in a small bowl and mix with the pressed garlic to form a paste.
2. Brush both sides of the tuna with soy sauce. Massage the spice mixture into both sides and set aside for 5 minutes at room temperaure.
3. Heat a large nonstick skillet or a seasoned cast-iron skillet over high heat until smoking. Add the oil, then slip tuna into the pan. Cook 2 minutes, then turn and continue cooking to desired doneness, about 1 minute for rare, 2 minutes for medium rare, or 4 minutes for well done. Transfer to cutting board and let rest at room temperature for 5 minutes.
4. Meanwhile, arrange 1 1/2 cups salad greens and 1/4 of the cucumber and carrot on each of four plates. Slice the tuna into 1/4-inch-thick strips, cutting against the grain so the steak does not fall apart. Lay 1/4 of the slices over each salad. Drizzle 2 teaspoons balsamic vinegar over each portion. Serve at once.
