Bring a large pot of salted water to a boil and cook noodles according to package instructions.
Heat a pan with the oil and add the green onion, garlic, ginger and saute until the garlic is just golden brown.
Add the chopped broccoli, edamame, carrots, bell pepper and vegetable broth. Let saute for 5-7 minutes, covering halfway or until broccoli is fork tender.
Add in all remaining ingredients (aside from the scallions) and the cooked noodles. Simmer for 5 minutes to allow the noodles and veggies to absorb the flavors.
Garnish with chopped cilantro, red pepper flakes and sesame seeds if desired.
