Add the strawberry yogurt to a large bowl followed by the sliced strawberries, sugar, and Cool Whip.

Use a spoon or spatula to fold everything together until it is well combined.

Spoon the mixture into the premade graham cracker crust. If the crust has a plastic lid, place it over the pie and crimp the edges of the pie dish to hold it in place.

Place in freezer for 4 hours or overnight.

When ready to serve, let the pie sit out for 15-20 minutes to allow it to soften. Garnish with fresh strawberries then cut and serve.
