1 pound very fresh tuna steak, 1-inch thick (I bought fresh tuna steaks from Costco and used 2 filtes- they were probably closer to 2 inches thick)
Kosher salt and freshly ground black pepper
1 lime, zest grated
3 tablespoons freshly squeezed lime juice (2 limes)
1/2 teaspoon wasabi powder (I didn't use this)
1 teaspoon soy sauce
5 dashes hot sauce (I used Frank's red hot)
1 firm, ripe Hass avocado, medium-diced (I used 2 avos b/c I think I had a little more than 1 lb of fish)
1/4 red onion, chopped (I used closer to 1/2 c)
1 tablespoon minced scallion, white and green parts
1 tablespoon toasted sesame seeds
9 hot dog rolls, grilled or toasted
1 bunch baby arugula, washed and spun dry
Heat a charcoal grill with hot coals. Brush the grill with oil.
Brush both sides of the tuna with olive oil and sprinkle generously with salt and pepper. Cook the tuna over the medium hot on the grill for 5-7 minutes on each side. This will cook it all the way through. The original recipe called for 2 1/2 min. on each side. Allow to cool and cut into cubes.
(If you don’t want to heat a grill, you can sear the tuna in a dry saute pan over high heat. Heat the pan for 2 minutes, add the tuna steaks and cook for 1 1/2 to 2 minutes on each side until seared on the outside and still raw inside).
For the dressing, whisk together 2 tablespoons of olive oil, the lime zest, lime juice, wasabi powder, soy sauce, hot sauce, 2 teaspoons kosher salt, and 1 teaspoon pepper in a small bowl. Toss the avocado in the dressing and then add the tuna, red onion, scallion, and sesame seeds. Line the rolls with arugula leaves, fill with the tuna mixture, and serve.
