Green Beans with Pink Soba Noodles, Miso, Pecans, Pink Pickled Ginger, & Purple Umeboshi plums

I had something like this at a fantastic Japanese restaurant in Soho, London called Koya. Pink soba noodles are flavored with plums and you can also buy them in green (green tea-flavored), black or white. They cook very quickly and have no gluten (though you should check the label, as some soba noodles contain wheat). In this recipe, you eat them cold—sounds weird, huh? Actually it works: the hot beans, cold noodles, salty fudgy taste of nuts and miso, and vinegary heat of the ginger.
