1) Bring a large pot of water to a boil. Add noodles and cook per package directions. Soba noodles usually cook for 4 minutes in boiling water. Use a timer; a minute too long and they turn to a mushy mess. Drain and rinse noodles well. Set aside.
2) Using a blender or food processor, combine ginger, garlic, tamari, agave, tomato paste, vinegar, sesame oil and hot sauce until smooth.
3) If making a salad, gently mix noodles with thinly cut vegetables and dressing. Let sit for at least so minutes so flavors meld. Sprinkle with toasted sesame seeds.
4) For a hot noodle dish, prepare all of the remaining ingredients for a quick stir-fry. In a large skillet or wok, heat oil over high heat. Add broccoli slaw or cabbage and carrots and stir-fry for 2 minutes. Then add white portion of the scallions and edamame and toss for another minute or two. Pour drained noodles and ginger sauce in with the vegetables and carefully toss to heat through and mix. Toss in the green portion of the scallions and top with sesame seeds. Serve immediately.
