For the Sandwich

Method

Preparing the Ahi Tuna

  1. 1

    Marinate the Tuna

    In a bowl, combine the olive oil, soy sauce, sesame oil, salt, and black pepper. Whisk until well mixed. Add the Ahi tuna steaks to the marinade and allow them to sit for at least 15 minutes.

  2. 2

    Sear the Tuna

    Heat a non-stick skillet over medium-high heat. Once hot, remove the tuna from the marinade, letting excess drip off. Sprinkle black sesame seeds on both sides of the tuna steaks. Sear the tuna steaks in the skillet for 1-2 minutes on each side for medium-rare, or longer to your desired doneness. Remove from heat and let them rest for a few minutes before slicing.

Assembling the Sandwich

  1. 3

    Prep the Bread

    While the tuna is resting, slice the ciabatta bread in half horizontally. Lightly toast them in the same skillet until golden brown.

  2. 4

    Prepare the Avocado

    Slice the avocado in half, remove the pit, and scoop the flesh into a bowl. Mash it with a fork and season with a pinch of salt and a squeeze of lemon juice.

  3. 5

    Slice the Tomato

    Slice the tomato into thin rounds.

  4. 6

    Mix the Sauce

    In a small bowl, mix the mayonnaise and Sriracha sauce until well combined.

  5. 7

    Build the Sandwich

    Spread the mashed avocado on the bottom half of the toasted ciabatta. Layer the arugula, sliced tomato, and the sliced Ahi tuna on top. Drizzle with the Sriracha mayo sauce and top with the other half of the ciabatta.

  6. 8

    Serve

    Cut the sandwich in half if desired and serve immediately with a wedge of lemon on the side.
