1. In a small bowl, whisk together soy sauce, sesame oil, rice vinegar, honey, grated ginger, sesame seeds, salt, and pepper until well combined. Taste and adjust—this becomes your salad dressing too, so it should taste balanced on its own.
2. Place the tuna in a shallow dish and pour half of the marinade over it, turning to coat evenly on all sides. Let marinate for exactly 15 minutes at room temperature—don’t go longer or the acid will start “cooking” the fish.
3. Heat vegetable oil in a grill pan or heavy skillet over high heat until almost smoking—this is crucial for getting that perfect sear. The pan should be hot enough that a drop of water sizzles immediately.
4. Carefully place the marinated tuna in the hot pan and sear for 1-2 minutes per side for rare doneness. Don’t move or press the fish—just let it develop that gorgeous golden crust. For medium-rare, go 2-3 minutes per side.
5. Remove tuna from heat and let rest for 2-3 minutes before slicing—this helps the juices redistribute and makes cleaner cuts. Using a very sharp knife, slice against the grain into 1/4-inch thick pieces.
6. In a large bowl, toss the mixed salad greens with the remaining marinade until evenly coated. The greens should be lightly dressed, not drowning in sauce.
7. Arrange the dressed greens on serving plates and top with the beautiful sliced tuna, fanning the pieces to show off that perfect pink center. Drizzle any remaining marinade over the tuna for extra flavor and shine.
8. Serve immediately while the contrast between warm tuna and cool greens is at its peak. Garnish with extra sesame seeds if desired.
