Heat oven to 350 degrees F. Lightly grease 9-inch square pan.
Stir together coconut, sugar, flour, and salt in large bowl. Add egg whites, whole egg, and almond extract; stir until well blended. Stir in chocolate pieces. Spread mixture into prepared pan, covering all chocolate pieces with coconut mixture. Bake 20 to 25 minutes or until lightly browned. Cover with foil; allow to stand at room temperature about 8 hours or overnight. Cut into bars.
VARIATION: Omit chocolate pieces in batter. Immediately after removing pan from oven, place desired number of chocolate pieces on top, pressing down lightly. Cool completely. Cut into bars.
