Hope you'll try Emilee's suggestion for a search - you will find a lot I'm sure. I cut out Jean Carper's column from a USA Weekend Sunday magazine a couple of weeks ago. Sorry but I have not tried either recipe. One does call for strawberries but you could substitute a fruit of your choice. I wanted to post it since it used both the orange juice and pineapple you asked for.

Tropical Cooler

2 cups orange juice (from carton or frozen reconstituted)
1 cup sliced fresh strawberries
1 8-oz. can crushed pineapple in juice (or 1 cup fresh pineapple chunks)

Process all in blender until smooth. If too thick, add carbonated water to taste. Pour over crushed ice. Garnish with mint sprigs.

Serves 4

Grape-Cherry Cooler

2 cups 100% grape juice from Concord grapes (bottled or frozen reconstituted)
2 TBSP lemon juice
1 cup frozen dark sweet pitted cherries
1/2 tsp cinnamon
Optional: 1/2 cup plain nonfat yogurt

Process all in blender until smooth. Pour over crushed ice.

(Note: Lemon juice and yogurt help lower the "glycemic index" of the grape juice, reducing its ability to spike blood sugar. Cinnamon boosts insulin activity to help process the sugar.)

Jean Carper as you probably guessed is an "Eat Smart" author who knows her nutrition.
