Mix the pink grapefruit juice with the vodka and simple syrup.
Place the grapefruit mixture into an ice cream machine or a sorbet maker, and freeze according to the manufacturers directions. Serve at once or transfer to a freezer container and freeze until ready to serve. Place the sorbet in the refrigerator for 15 minutes before serving to allow it to soften slightly.
To serve, hollow out 2 grapefruit halves and divide half the strawberry slices evenly among the halves. Scoop the sorbet over the strawberries, then cover with the remaining berries.
