Deconstructed sushi in a bowl — tuna, cucumber, rice, soy sauce. A low calorie Wednesday dinner that feels playful and takes zero sushi-rolling skills.
Slice the cucumber into thin half-moons and gently toss with 1 tablespoon rice vinegar. Let marinate while you prepare other components.
Cube the tuna into 1/2-inch pieces for an even bite, making sure to use a sharp knife for clean cuts.
In a small bowl, whisk together soy sauce, sesame oil, and wasabi paste for the sauce. Taste and adjust the wasabi for desired heat.
Lay cooked rice in two shallow bowls; fluff it with a fork for optimal texture and let it cool slightly to prevent wilting the toppings.
Arrange cucumber, tuna, and sliced green onion atop the rice, then drizzle with the prepared sauce. Tear nori into strips and scatter over the bowls, finishing with a sprinkle of sesame seeds.
