1 medium fresh pineapple, peeled and cut into chunks (about 5 cups)
1 quart fresh strawberries, quartered
2 cups green grapes
In a microwave-safe bowl, stir the sugar, cornstarch and apricot nectar until smooth. Microwave, uncovered, on high until slightly thickened, 4-6 minutes, stirring every 2 minutes. Stir in the vanilla. Refrigerate.
In a large bowl, combine the fruit. Drizzle with dressing; gently toss to coat. Cover and refrigerate until serving.
