Begin by preparing the ahi tuna steaks; gently pat them dry with paper towels to remove excess moisture, ensuring a nice sear.
In a shallow dish, mix together the soy sauce and sesame oil until well-combined. Place the tuna steaks in the marinade, ensuring each side is thoroughly coated. Allow them to marinate for about 10 minutes for enhanced flavor.
Spread the sesame seeds out on a flat plate. Firmly press each tuna steak into the seeds, ensuring both sides are evenly coated to create a crunchy crust.
Heat olive oil in a non-stick skillet over medium-high heat. When the oil is shimmering, carefully place the sesame-crusted tuna steaks in the skillet. Sear for 1-2 minutes per side for medium-rare, adjusting the cooking time if you prefer a different level of doneness. Once cooked to your liking, remove the tuna from the skillet and set aside to rest for a few minutes.
While the tuna rests, prepare the salad. In a large mixing bowl, combine the mixed salad greens, sliced cucumber, avocado wedges, julienned carrot, and thinly sliced radishes. Gently toss to combine the ingredients evenly.
In a small bowl, whisk together the rice vinegar, honey, and a pinch of salt and pepper to create a delicious dressing. Drizzle the dressing over the salad and toss everything together until the vegetables are well coated.
Once the tuna has rested, slice it into thin strips, allowing the beautiful sesame crust to shine. Arrange the slices artfully on top of the dressed salad.
To finish, sprinkle additional toasted sesame seeds over the top for extra crunch and an appealing garnish.
Notes
Serve the salad in shallow bowls for an elegant presentation.
