Cook the instant noodles, drain, and set aside.
Heat the olive oil in a large pan over medium-high heat. Add the stir fry veggies and toss to coat. Cook for 4-5 minutes, stirring a few times until the veggies are tender crisp and browning in spots.
Add the ginger and cook for another minute until fragrant.
Add the chicken and cook until heated through, another 1-2 minutes.
Add the teriyaki sauce, cooked noodles, and noodle sauce packets. Toss everything together until evenly coated in the sauce. Garnish with toasted sesame seeds, sliced green onion, and crunchy chili onion or chili oil, if desired.
