Servings 2

Ingredients

For the tuna:

  • 2 tablespoons soy sauce
  • 2 tablespoons sesame oil
  • ¼ teaspoon garlic powder
  • ¼ teaspoon kosher salt
  • ¼ teaspoon freshly ground black pepper
  • 2 (8 ounce) ahi tuna steaks

For the wasabi mayo:

  • ½ cup mayonnaise
  • 2 teaspoons soy sauce
  • 1 teaspoon lemon juice
  • 2 teaspoons wasabi paste

For the fried wontons:

  • 6 ounces wonton wraps sliced in half to make triangles
  • 1 quart vegetable oil

Additional ingredients:

  • 1 ½ cups prepared seaweed salad
  • 1 cup grape or cherry tomatoes quartered
  • 1 avocado halved, seeded, peeled and diced
  • 1 teaspoon sesame seeds
  • Sriracha sauce
  • Additional soy sauce for dipping

Instructions

  • Prepare the marinade for the tuna by whisking together soy sauce, sesame oil, garlic powder, salt, and pepper. Place tuna steaks in a zip-top bag and pour in marinade. Coat well and place in your refrigerator.
  • While tuna is marinating, prepare wasabi mayo by whisking ingredients together in a small bowl. Cover and refrigerate.
  • Prepare fried wontons by heating vegetable oil in a large heavy pot or skillet with high sides over medium high heat (2 inches deep) until it reaches 350 degrees F, using a deep-fry thermometer.
  • Add wontons to oil and fry, working in batches, until chips are slightly puffy and golden brown, stirring gently (about 1 minute). Adjust heat as necessary to maintain a temperature of 350 degrees F. Carefully transfer to a large plate or baking sheet lined with paper towels.

Sear the tuna:

  • Heat a nonstick skillet over medium high heat until hot. Remove tuna steaks from marinade and sear for 1 minute on each side, or until desired temperature is met (my tuna steaks were 1 ½ inches thick and seared 1 minute on each side to yield rare). *The FDA recommends tuna steak be cooked to an internal temp of at least 145 degrees F using a digital instant read thermometer.
  • Remove tuna steaks from pan and thinly slice into approximately 1-inch pieces.

Prepare the nachos:

  • Assemble nachos by evenly distributing fried wontons onto 2 plates. Top each with ½ of the seaweed salad, followed by the sliced tuna, avocado, tomatoes, and sesame seeds.
  • Drizzle with desired amount of wasabi mayo and sriracha. Serve with additional soy sauce if desired.
