1Heat oven to 400°F. Make pie crust as directed on box for One-Crust Baked Shell, using 9-inch glass pie plate.
2While shell is cooling, make pudding according to package directions. Pour hot pudding into cooled baked shell. Let stand 2 minutes or until slightly set. Gently sprinkle marshmallows over top of pudding; sprinkle with crushed candies.
3Cover pie with foil, tenting foil slightly to prevent marshmallows from sticking. Cool 15 minutes then refrigerate at least 2 hours or until chilled. Decorate center of pie with 2 or 3 whole peppermints before serving, if desired.
