Soba noodles tossed with cucumber, scallions and a light yet creamy sesame-ginger-tahini sauce. This would be a great vegan potluck dish, but note that it is best when served promptly, as the salt will draw out the water from the cucumbers and dilute the flavors. It can be gluten-free if you buy gluten-free soba noodles, soy sauce and miso.
