For Noodles:
For Sauce:
For Vegetables & Chicken:
In a large pot of salted boiling water, cook the noodles until tender. Drain and return to the cooking pot to keep warm.
Meanwhile, combine the soy sauce, brown sugar, sesame oil, 1 Tbsp oil, vinegar, hoisin sauce, sweet chili sauce, ginger (optional) and garlic in a small pot and bring to a simmer. When the noodles are ready, toss them with the sauce in the cooking pot.
In a large pan over high heat, stir-fry the broccoli in batches until bright green and crisp-tender, adding oil as necessary. Add the broccoli to the noodles as it’s cooked along with the carrots and peppers.
Cook the chicken in 1 Tbsp oil in a large pan over medium-high heat until cooked through. Add to the noodle-vegetable mixture and toss to combine thoroughly.
