Boil the noodles according to package instructions. Drain and toss with 1 tablespoon sesame oil and 1 tablespoon soy sauce to prevent sticking. Set aside.
Season the chicken with salt and pepper. Dredge each piece first in beaten eggs, then in a mix of cornstarch and flour.
Heat vegetable oil in a skillet over medium-high heat. Fry the chicken in batches until golden brown and crispy, about 4–5 minutes. Drain on a paper towel-lined plate.
In a saucepan over medium heat, combine soy sauce, honey, brown sugar, rice vinegar, sesame oil, hoisin sauce, and garlic. Bring to a simmer.
Add the cornstarch slurry and stir until the sauce thickens, about 2–3 minutes.
Toss the cooked noodles in about half of the sauce. Top with crispy chicken and drizzle the remaining sauce over everything.
Garnish with green onions, sesame seeds, and any additional toppings you like.
