Mix yogurt if not pre-mixed. Spoon into ice cube tray. Freeze until
completely frozen, 3-4 hours. Remove cubes from tray and place in bowl of
electric food processor. Process until finely chopped. Add strawberries
and orange peel. Process just until almost smooth. Serve immediately, or
place in freezer and stir occasionally until firm enough to scoop, 1-2
hours. Serves 4.
Flavor variations -
