Jane, perhaps you could use this recipe as a base for your salad and experiment with more "tropical" ingredients. I use the Kroger Pina Colada Lite brand yogurt and blend the marshmallow creme with it first for easy mixing. I sort of came up with the marshmallow creme idea when it needed just a bit more sweetness and body. Good luck on your state fair entry and let us know what you decide.
