Steph's Mile High Strawberry Pie

Bake pie shell and allow to cool.

Place strawberries, sugar, egg whites and lemon juice in large bowl of electric mixer.  Beat until mixture is stiff and almost reaches the top of the bowl, about 25 to 30 minutes.  This is best mixed in a standard mixer.  Whip cream in separate bowl and stir in vanilla, fold into strawberry mixture.  Turn into baked pastry shell and freeze several hours or overnight.  Remove from freezer just prior to serving.  May have to chill mixture before putting in pie crust then place in freezer.
