Preheat oven to 350 degrees F. Line a large baking sheet with foil; lightly coat with cooking spray. Place wontons flat on the baking sheet; lightly coat with additional cooking spray. Sprinkle lightly with sugar. Bake for 6 to 8 minutes or until golden brown and crisp. Remove from oven; cool slightly.
Meanwhile, in a medium bowl combine the 1/2 cup sliced strawberries and the kiwifruits.
To assemble, place one baked wonton wrapper on each of four dessert plates. Top each with some of the yogurt. Divide the fruit mixture evenly among the stacks. Add another baked wonton. Top with remaining yogurt. Garnish each stack with a strawberry half.
