Light and luscious. If necessary, a 10-ounce package of frozen, sweetened strawberries may be substituted for fresh, but reduce to taste the amount of sugar in the recipe.
Combine strawberries and sugar, and let sit for about 30 minutes. Put berries, lemon juice, and egg whites in large bowl and beat with electric mixer on medium speed until stiff peaks form. (This may take 15 minutes.) Fold in the whipped cream gently. Pile high in pie crust and freeze before serving.
