Sushi-grade tuna, spicy mayo, rice, sesame seeds. This bowl gives you the sushi bar experience at your desk — high protein and no chopstick skills required.
Dice the sushi-grade tuna into ½-inch cubes and set aside in a mixing bowl.
Prepare the spicy mayo by whisking together mayonnaise and sriracha until smooth, then gently toss with tuna cubes to coat evenly.
Slice the scallions, avocado, and cucumber; set them aside for assembly.
Spread warm cooked rice evenly into 2 serving bowls and sprinkle with rice vinegar for added flavor and moisture.
Top the rice with the spicy tuna mixture, sliced avocado, cucumber, and scallions. Drizzle soy sauce and toasted sesame oil, then finish with a generous sprinkle of sesame seeds.
