(NOAH) Chanko recipe from the Noah dojo

This recipe appears to be one that comes directly from Noah (the other one comes from Diamond Ring, and had most of the ingredients eaten by Junta Miyawaki).
I am afraid that this recipe does not give any cooking times, nor quantities.

MAIN INGREDIENTS (amounts are optional, so feel free to use how much or little as you please)
Chinese cabbage
Green ion
Daikon Radish (grated and chopped)
Mushrooms (Shitake, Shimeji, Enoki)
Chicken
Bean sprouts
Spinach
Tofu
Coconut

Equivalent amounts of soy sauce, vinegar, dashi and mirin.
Use appropriate amounts of garlic, yuzu pepper and ground sesame seeds.

① Chop the vegetables, and de-stalk the mushrooms
② Put the chicken and the vegetables into the pan, and then the mushrooms. Once it is boiled ( add enough water to cover it) add the coconut at the end.
③ Make a sauce by combining soy sauce, vinegar, dashi and mirin, add the grated radish to the sauce. This is to make it stronger.
④ Once cooked, add Daikon radish to the ingredients, add the garlic, sesame seeds and Yuzukoshō (Japanese seasoning) as you like.

Dashi: Japanese soup base. You can make this very simply by soaking a sheet of Kombu in cold water, and leaving it to rest for about 15 - 20 minutes. Please remove the Kombu and discard before use.
Mirin: This is a sweet rice wine that adds a flavor to a dish (it is for cooking, not drinking purposes, so it is hardly the equivalent to sherry, so I don't recommend you keep a glass on the side). You should be able to source mirin at supermarkets or Asian stores. However (and I speak from experience), this can sometimes be hard, but an alternative is to use dry sherry, dry white wine or rice vinegar as a substitute. Mix in about 1/2 teaspoon of sugar per tablespoon.
