Frozen Strawberry Squares

Frozen Strawberry Squares

1 cup flour
¼ cup brown sugar
½ cup chopped walnuts
½ cup melted margarine

2 egg whites
1 cup sugar
9 oz. Cool Whip
16 oz. Strawberries
2 tablespoons lemon juice

Preheat oven to 350. Mix flour, brown sugar, walnuts and margarine to crumb consistency. Bake mixture for 20 minutes in a shallow pan, stirring occasionally. Sprinkle 2/3 of the crumb mixture into a 9x13 pan, to cover the bottom of the pan.

Beat egg whites, sugar, strawberries, and lemon juice on high 10 minutes; fold in Cool Whip. Spoon mixture over crumbs. Top with remaining crumbs and freeze at least six hours.
