Fold 1/3 of the whites into the cheese mixture, then fold the lightened cheese mixture back into the remaining egg whites. finally, fold in the thawed whipped topping.

Puree raspberries in a blender or press through a sieve. Spread half of fluffy cheese filling into the cooled crust. Pour half of the raspberry puree over the filling and swirl it in with a knife. Repeat with remaining filling and raspberry puree. Freeze until firm.
