This one has an odd history of development. Its inception started with the one-pot meal concept of "Chanko-Nabe", which is a sort of Japanese stew fed to Sumo Wrestlers ... so they can gain weight! Mine isn't intended for that purpose, so don't fret. Chanko-Nabe often contains noodles and is served in massive portions with beer and rice (as part of the Sumo Wrestlers' diet)
. I'm not suggesting you eat like a Sumo Wrestler, but I AM saying that this soup must be good, if Sumo Wrestlers are so able and willing to eat such large quantities of it!
Ultimately, my version is a noodle-free, soy-ginger based chicken broth, with chicken simmering in the broth, for about an hour. Then, remove and break the chicken into large chunks. Add a variety of fresh vegetables and the chicken, simmer for a few minutes. You can really use just about anything. Broccoli, radishes, bean sprouts, green onions, leeks and/or different mushrooms might be some alternative additions. You could also throw some tofu, or Shirataki (Miracle) noodles
, in there! It's a full, warm, healthy and very tasty one-pot meal. Adjust seasoning with a little salt or soy sauce (it probably needs it, but ... be careful with that soy sauce. The carbs add up fast.)
.... EAT!(no beer ... no rice, though ... sorry to say!)
