To same skillet, add broccoli, carrots and green onions; stir to coat with oil. Add water; cover and cook 4 minutes, stirring once. Uncover and cook 1 minute longer or until vegetables are tender-crisp, stirring frequently. Transfer vegetables to bowl with peel.
To same skillet, add remaining 2 teaspoons vegetable oil; reduce heat to medium. Add chicken mixture and cook 6-7 minutes or until chicken is golden and no longer pink throughout, stirring frequently. Transfer chicken to bowl with cooked vegetables.
