COMBINE pesto, lemon peel and lemon juice in large, resealable plastic bag. Add chicken and vegetables; seal. Marinate in refrigerator for 1 hour.
THREAD chicken and vegetables alternately on 10-inch skewers; discard any remaining marinade.
PREHEAT grill or broiler. (Place kebabs on baking sheet if broiling.) Grill or broil for 5 minutes; turn over. Grill or broil for an additional 3 minutes or until vegetables are tender and chicken is cooked through. Season with salt and ground black pepper, if desired.
NOTE: If using wooden skewers, soak in water for 30 minutes before threading.
