How to Make It
In a large sieve, rinse the noodles under cold running water. Transfer them to a large bowl and cover with warm water. Let stand for 30 minutes. The noodles will be pliable but still have a crunchy bite. Drain well.
In a blender or a small food processor, finely chop the ginger. Add the miso, rice vinegar, soy sauce and sesame oil and blend until combined. Add the canola oil in a steady stream if using a blender, or in smaller batches if using a food processor, until the dressing is emulsified. Add 1/4 cup of warm water and blend until combined.
Transfer the noodles to a large serving bowl and use scissors to snip them into shorter lengths. Add the carrot, apple, pepper and cilantro. Toss with enough dressing to coat. Sprinkle with sesame seeds and serve immediately.
