Chop up scallions and garlic. Sauté in sesame oil with some grated ginger and set aside.
Mix up tahini or peanut butter, tamari and red wine vinegar and stir it up. Add water or green tea (if you have some) to thin it to a nice consistency. Adjust amounts of stuff as needed. Dump in the scallions and stuff.
Steam up some broccoli and fry some tofu and when your noodles are done (udon, soba or regular pasta), mix the sauce with the noodles and throw on the broccoli and tofu. Good hot or cold.
