Just cut up, mix and serve. An easy Korean-flavored instant pickle dish.
When I tried putting the leek-miso I made for samgyeopsal on cucumbers it was delicious, so I adapted it to make it into a proper recipe.
If you don't like spicy food, adjust the spiciness by varying the amount of gochujang and miso used. You can use plain salt instead of shio-koji (salt-fermented rice malt).
Enjoy Japanese food around the world.
