Ingredients
- ½ pound ahi tuna (sushi-grade, cubed)

- 2 tablespoons pickled ginger (finely chopped)
- 2 tablespoons green onions (chopped)

Instructions
- Step 1: In a bowl, combine the cubed tuna, soy sauce, sesame oil, chopped jalapeno (if using), pickled ginger, green onions, and sesame seeds. Gently toss to mix all ingredients evenly.
- Step 2: Cube the Persian cucumbers and avocado into small pieces similar in size to the tuna. Place each in a separate small bowl and season with half of the kosher salt individually.
- Step 3: Using a 1-cup measuring cup, start layering the stack by adding a few spoonfuls of the tuna mixture, then a layer of cucumber, followed by avocado, and finally sushi rice on top. Press gently to flatten the stack.
- Step 4: In a small bowl, make the spicy mayonnaise by mixing the mayonnaise, sriracha, soy sauce, and lime juice. Adjust the heat by adding more sriracha if desired.
- Step 5: Carefully invert the measuring cup onto a serving plate to release the stack. Repeat to assemble all four stacks.
- Step 6: Drizzle the spicy mayonnaise over each stack and sprinkle with additional sesame seeds. Serve with nori strips or wonton chips as a crunchy accompaniment.
Tips & Variations
- Use tamari instead of soy sauce for a gluten-free option.
- Skip the jalapeno or sriracha to make a milder version of this dish.
- Add a squeeze of fresh lime over each stack before serving for an extra burst of brightness.
- Try substituting the tuna with salmon for a different flavor profile.
Storage
Keep any leftovers covered in an airtight container refrigerated for up to 24 hours. For best texture and freshness, it’s recommended to consume the stacks immediately after assembling. Avoid storing with the spicy mayonnaise on top; add it just before serving. Reheating is not recommended as the ingredients are best enjoyed fresh and chilled.
