Cut about 1/3 of a daikon radish into 1 cm pieces or less.

Boil in a microwave oven (600W) for about 7 minutes

When you take it out, put it in a pot, add the seasonings and canned tuna in the ingredients, cover with a drop-lid and wait for it to come to a boil.

Simmer over low heat for 5 to 10 minutes, then turn off the heat.

Let it sit overnight to let the flavors soak in and it tastes great. You can also add green onions when serving.
