How and where and more how ~ Go to the food blog 101 Cookbooks. Look at the ingredients list for soba and open that. The dish is called Otsu (means nothing to me). This is very tasty. It's in steps, perhaps too many, but is simple.
Drain, squash, cube, and fry tofu (I chose to fry, a change from the recipe). The cook recommends toasting the tofu in a heavy pan, which might be even better than frying.
Mix up the dressing, and don't bother with a food processor. Just use a microplaner to grate the ginger, then whisk all (I heated the honey in microwave; agave would be good). Pour the dressing over the tofu, for a chance to absorb the good stuff.
Boil up the noodles, drain under cold water and mix with a tad of oil.
Mix it all together, noodles, dressing, tofu, cucumber, cilantro, scallions, and probably something else.
Do not put this in the freezer.
