Preheat oven to 350 degrees.

In a food processor, pulse Oreo cookies to form crumbs. Stir in melted butter.

Press crumb mixture over the bottom and up the sides of a 9-inch pie plate.

Bake in preheated oven for 8-10 minutes; cool completely.

Meanwhile, with an electric or stand mixer, beat melted chocolate with sweetened condensed milk until smooth.

Fold in thawed whipped topping.

Spoon chocolate mixture into prepared crust and smooth top. (If you can' t quite fit it all,just serve the extra as mousse.)

Refrigerate for at least 4 hours, or until firm.

To make the ganache, heat 1/2 cup cream to just a simmer. Pour over semi-sweet chocolate in a small bowl and whisk until shiny and smooth; cool to room temperature (mixture should still be runny enough to drizzle).

Before serving, arrange strawberry halves over pie.

Drizzle chocolate ganache over strawberries. Serve immediately, or return to refrigerator until serving.
