  • 4 steaks fresh tuna 3/4 inch thick (about 4-6 ounces each
  • tuna choices such as Ahi or Tombo)
  • 1 tablespoon peanut oil
  • 1/2 cup mayonnaise
  • 1 teaspoon white miso
  • 1 teaspoon Asian sesame oil
  • 2 teaspoons minced ginger
  • 1 teaspoon rice wine vinegar
  • 3 tablespoons finely chopped green onion
  • 1 teaspoon sugar
  • 1/2 teaspoon soy sauce
  • 1/2 medium English hothouse cucumber, unpeeled, thinly sliced
  • 1 avocado, peeled, seeded and thinly sliced
  • 8 medium red radishes, thinly sliced
  • 8 slices crusty white bread


Season fish with a sprinkling of salt and pepper.

Heat a heavy ridged grill pan or cast iron frying pan over medium high heat. Coat generously with oil. Add fish and cook 1 1/2 to 2 minutes. Turn and cook 2 minutes more (tester -- I prefer the tuna to be medium rare). Remove fish and set aside.

Combine all Asian mayonnaise ingredients in a bowl and whisk until smooth.

To assemble each sandwich, generously spread both pieces of bread with mayonnaise. Cover one side with a layer of cucumber followed by a layer each of radish and avocado. Sprinkle lightly with salt. Top with the warm fish and the other slice of bread. Cut sandwich in half and serve.
