it's hot, but these noodles aren't the answer

My love of miso & soba noodles led me to this dish, but unfortunately it was a complete "never again" for us. It's possible that our choice of vegetables (there were a lot of radishes) or the previously-frozen ginger were to blame, but the dish was bitter and not very interesting. I could see something similar working, perhaps with some herbs (thai basil and mint?) and with 'sweeter' veggies (carrots and snap peas?).
