Cut the baby bok choy in half and drizzle with a bit of toasted sesame oil.
Toss the snap peas, cherry tomatoes, and shredded carrot in a separate bowl.
Pan-Sear the Tuna:
Heat a grill pan or skillet over high heat.
Coat the tuna fillets with toasted sesame oil and season with salt and pepper.
Place the tuna and the bok choy into the pan and grill for about 2-3 minutes per side for medium-rare (cook longer if you'd like the tuna more well done).
Cook the Snap Peas:
Add the snap peas to the grill pan and cook for about 1-2 minutes, just until they develop a slight char but remain crisp.
Cook and Chill the Noodles:
Cook the soba noodles according to package instructions.
Drain, rinse under cold water to stop the cooking, and toss with 1 tablespoon toasted sesame oil to prevent sticking.
Make the Ginger Soy Dressing:
In a small bowl, whisk together 2 tablespoon sesame oil, soy sauce, fish sauce, grated ginger, and lime juice and zest.
Assemble the Salad:
Slice the seared tuna into strips.
On a serving platter or individual bowls, arrange the cold noodles as a base.
Top with bok choy, snap peas, cherry tomatoes, shredded carrots, and avocado slices.
Lay the sliced tuna over the salad and drizzle with the ginger soy dressing.
Sprinkle with chopped cilantro, green onions, and sesame seeds.
Serve with lime wedges on the side.
Notes
Tuna Selection: For the best quality, buy sushi-grade tuna. It should be firm, deep red, and free of fishy smell.
Cooking Time: Tuna cooks quickly, so monitor carefully to avoid overcooking. Aim for medium-rare for optimal flavor and texture.
Bok Choy Alternatives: If baby bok choy is unavailable, substitute napa cabbage or other leafy greens.
Dressing Customization: Adjust the dressing to your taste by adding more lime juice for acidity or honey for sweetness.
Garnishes: Add crushed peanuts or cashews for extra crunch.
