2/3 cup fresh orange juice
1/3 cup fresh lemon juice
1/3 cup packed brown sugar
1/2 teaspoon grated orange zest
1/2 teaspoon grated lemon zest
1 teaspoon vanilla extract
2 cups cubed fresh pineapple
2 cups strawberries, hulled and sliced
3 kiwi fruit, peeled and sliced
2 oranges, peeled and sectioned
1 cup seedless red grapes, halved
1 cup blueberries
1 cup blackberries
Bring orange juice, lemon juice, brown sugar, orange zest, and lemon zest to a boil in a saucepan over medium-high heat. Reduce heat to medium-low, and simmer until slightly thickened, about 5 minutes. Remove from heat, and stir in vanilla extract. Set aside to cool.
Place pineapple, strawberries, kiwi, orange sections, grapes, blueberries and blackberries in a large serving bowl. Pour the cooled sauce over the fruit. Cover and refrigerate for 3 to 4 hours before serving.
