Toss shrimp with 1/4 cup salad dressing; cover and refrigerate at least 30 minutes. Drain; thread shrimp onto skewers. Grill, covered, 4-6 inches above white-hot coals for about 4 minutes or until pink and done. Remove shrimp from skewers and place in a large salad bowl. Add remaining ingredients and toss with remaining 1/4 cup salad dressing. Serve at once.
