Heat oven to 450°F. Bake pie crust as directed on box for One-Crust Baked Shell, using 9-inch glass pie plate. Cool on cooling rack 15 minutes.
Meanwhile, in 1-quart saucepan, mix gelatin and orange juice; let stand 1 minute. Cook and stir over medium heat until dissolved. In small bowl, beat cream cheese, powdered sugar and orange peel with electric mixer on medium speed until smooth and fluffy. Gradually add softened gelatin; blend well. Refrigerate until slightly thickened, about 15 minutes.
In large bowl, beat whipping cream with electric mixer on high speed until stiff peaks form. Fold whipped cream into orange mixture; gently fold in chopped oranges. Spoon into crust. Refrigerate until firm, about 2 hours. Garnish with additional orange peel, if desired. Top each serving with dollop of yogurt. Cover and refrigerate any remaining pie.
