In a small saucepan, bring vinegar and lime juice to a boil. In a medium bowl, combine the sugar, salt, mustard, celery seed and paprika. Add lime juice mixture and stir until sugar dissolves. Whisk in oil and onion until dressing is well mixed and slightly thickened; transfer to a carafe or serving dish. Chill.
Just before serving, place greens in a large bowl. Arrange fruit on a plate or shallow bowl and sprinkle with coconut. Pass greens, fruit and dressing separately or place on a buffet.
