Pour water into the bowl you want to use. Add something to serve as 'dashi.' For example, 'Niboshi' (dried fish), 'dried shiitake,' 'Katsuobushi,' or 'Konbu.' If you don't have any, it's okay.

Add vegetables you like. Today, I add carrots, potatoes, and onion.

Green peppers and eggplants are also very common to add to miso soup. Canned tuna, eggs, and canned sardines are also very good.

Bring the water to a boil over high heat. When the vegetables are ready, add miso and mix gently.

It's ready!
