1. Steam the rice and leave it at room temperature

2. Cut the cucumber into small cubes

3. Sample the rice into a larger container for easy mixing, and mix in the tuna, cucumber, and nori

4. Wear disposable work gloves, and mix in the mayo, salsa, tuna roe, and black sesame seeds, and drizzle some white vinegar onto the gloves to taste. White vinegar drops to the gloves to continue to mix evenly, you can try the flavor

5. Mixed well and kneaded into a rice ball, eat ~ lazy people can also be directly with a spoon followed by the basin to eat, that is more refreshing!
