4. Slice the Vegetables: While the shrimp is cooking, thinly slice the cucumber and avocado. You can also chop the green onions for garnish.

5. Assemble the Stacks:
– Use a round mold or a small bowl for stacking.
– Start with a layer of sushi rice, pressing down gently.
– Add a layer of sliced cucumber.
