Marinate sliced chicken with soy sauce and cornstarch for 10–15 minutes to lock in moisture and flavor.
Whisk all sauce ingredients together until fully combined and set aside for later use.
Heat oil in a wok and sear chicken until lightly golden and cooked through, then remove.
Stir fry vegetables over high heat until crisp-tender and vibrant in color.
Return chicken to pan, pour in sauce, and toss until everything is evenly coated and thickened.
Let rest briefly before serving to enhance texture and flavor absorption.
