1Heat gas or charcoal grill. Alternately thread shrimp, zucchini, bell pepper and pineapple onto skewers, leaving space between pieces.
2In small bowl, mix taco seasoning mix, lime juice and oil; brush over kabobs. Reserve remaining mixture.
3Place kabobs on grill over medium heat. Cook uncovered 6 to 15 minutes, turning once and brushing 2 to 3 times with reserved taco seasoning mixture, until shrimp is pink and vegetables are tender.
