1 cup Fresh blueberries
1 cup Fresh strawberries, unsweetened
1 cup pineapple and orange juice blend
1 cup fat-free plain vanilla yogurt
2 teaspoons sugar or sugar substitute such as Splenda.
6 ice cubes
Place the blueberries, strawberries, juice, yogurt and sugar into the container of a blender. Process until smooth.
Add the ice cubes, and blend until small enough to fit through a straw, but large enough to crunch on.
Pour into glasses, and drink through straws.
