  3. Step 3: Pour the dressing over the tuna and avocado mixture. Add 2 tbsp thinly sliced green onions, a pinch of salt, and a pinch of black pepper. Toss gently to coat evenly.
  4. Step 4: Plate the tartare in small mounds or using a ring mold, then sprinkle 1 tsp toasted sesame seeds on top before serving chilled.
