Toss shrimp with 1 tablespoon lime juice, lime peel, garlic and 1 tablespoon Hellmann's® or Best Foods® Mayonnaise Dressing with Olive Oil. Marinate 15 minutes. Remove shrimp from marinade, discarding marinade. Grill or broil, turning once, until shrimp turn pink; set aside.
Meanwhile, in medium bowl, combine mango, papaya, red onion, remaining Mayonnaise Dressing, remaining 1 tablespoon lime juice and parsley. To serve, spoon mango mixture into margarita glasses or glass dishes and evenly top with shrimp. Garnish, if desired, with lime wedges.
