Cook according to package directions; drain and set aside.
Add all ingredients to a small bowl and whisk to combine; set aside.
To a large skillet add the oils, chicken, and cook over medium-high heat for about 5 minutes, flipping intermittently so chicken cooks evenly.
When chicken is about 90% cooked through, add the garlic and cook for about 1 minute or until fragrant, stirring often.
Add the broccoli, carrots, snap peas, baby corn, optional vegetables, add the sauce, stir, cover and cook for about 3 minutes or until vegetables are crisp-tender; stir intermittently.
Turn off the heat, add the noodles, and toss well to combine; I find adding the noodles in batches and tossing as you go is easier than trying to incorporate them all at once. If your skillet isn’t large enough to accommodate the noodles, transfer the chicken and vegetables to a large bowl before adding the noodles.
Garnish with green onions, add soy sauce if desired, and serve immediately.
