Prep the veggies ahead of time. Cover with a slightly damp paper towel and set off to the side.
FOR THE SAUCE: In a medium bowl or liquid measuring cup; whisk together the miso, 1/3 cup of tamari, chicken broth, peanut and toasted sesame oil, honey, lime juice, sriracha and white pepper. Set off to the side.
FOR THE CHICKEN: In a large bowl, toss the thin strips of chicken with 1 teaspoon peanut oil and 1 tablespoon tamari.
FOR THE STIR-FRY: Bring a large pot of water to a boil. Once at a boil, add in the noodles and cook for about 5 minutes before draining and rinsing with cold water.
Heat a teaspoon of peanut oil in a wok or large 12-inch chefs pan. Once hot, work in batches of two, add half of the chicken and cooking until it's browned and cook through, about 5 to 8 minutes total. Transfer the chicken to a medium bowl and set a side.
To the remaining oil in the pan (add a half teaspoon more if needed) add the inch-long green onion and the ginger and garlic. Cook for 30 seconds while continuously stirring, before scooting it to the outer edge of the wok. Add in the sugar snap peas, red bell pepper, carrot and zucchini. Toss to combine and cook until the vegetables start to glisten. About 2 minutes or so.
Add the shelled edamame, cooked chicken, soba noodles and then pour in the miso sauce. Use two wooden spoons or spatulas to toss it all together. Reduce heat to medium and cook for a few minutes, until the chicken is heated through.
Before serving sprinkle with the chopped cilantro.
Divide the stir-fry among shallow bowls or plates, top with thinly sliced green onions, a few extra cilantro leaves and a few drops more of sriracha.
