Peel the daikon. Cut into thin rectangles, or fine strips. Soak it in cold water till it's crisp. (about 15 minutes)
In a small bottle or a container, put in dressing ingredients and put on the cap, then shake it!
When daikon is crispy, drain the water, add tuna, bonito flakes and nori seaweed.
Pour ponzu dressing over when you eat.
I like ponzu, but you can try your favorite dressing! Enjoy!!
