Kiriboshi daikon: Soak kiriboshi daikon in water for 10 minutes, drain and cut in half.
Other ingredients: Cut a cucumber into thin strips. Boil moyashi for one minute and drain. Drain canned tuna.
Dressing: Combine sesame mayo dressing ingredients in a small bowl.
Toss: Put kiriboshi daikon, cucumber, moyashi, and tuna in a large bowl, add the dressing and toss.
Notes
Substitute: You can omit canned tuna to make it a vegetarian salad. Instead of cucumber and moyashi, you can use other vegetables such as carrots, lettuce, celery, and onion. Instead of vinegar, you can substitute it with lemon juice.
You can find the kiriboshi daikon package at a Japanese grocery store or online store.
The kiriboshi daikon will increase volume about four times when rehydrated with water. Start with half the size if you are eating kiriboshi daikon for the first time.
If you're not a fan of the smell of dried daikon radish, wash it thoroughly by squeezing it before rehydrating.
