How often have I told you that you can use pretty much any vegetables that you have on hand in a recipe?  A lot.  I know I repeat myself on this one, because it’s so often true.

Vegetable Udon Noodle Soup

This is a super delicate soup, very lightly flavored. Especially if you are using a less-sodium stock or broth, which I tend to do (and then add a bit of salt or some salty ingredient to my liking). Gary tends to glug in soy sauce when that is the case—and that’s why I also use less-sodium soy sauce in general, because when one glugs it in, one’s blood pressure doesn’t rise. I said one, not Gary.  I adore soy sauce, and I use it in things not Asian as well as almost every Asian recipe that I make.  I just know there needs to be a little bit of a …..gatekeeper?  Check and balance?  Anyway, if one is a glugger (Gary), less-sodium is a good thing.

Also, Japanese wheat noodles are very easy to overcook, so for this soup they get cooked on their own, then I just decided to give them  a rinse in cold water to stop the cooking.  Then I added them to the soup to reheat just before serving. That’s the way I’ve found it easier to not let them get mushy.  If you have more udon noodle control than I do—by all means, do your thing, and give me advice, please.

Also, I have made this with enoki mushrooms adding towards the end, and that was delicious.  I wish I had them in the photos….but I do not.
