1/2 cup unsweetened apple sauce
2-1/2 cups unbleached all purpose flour
1-1/2 tsp baking soda
1/2 tsp salt
1/4 cup butter, softened
1 cup light brown sugar
4 large egg whites
1 tsp vanilla extract
3/4 cup chopped walnuts, optional
baking spray

Preheat oven to 350°F. Grease two 8x5 inch loaf pans with baking spray.
In a medium bowl, combine flour, baking soda and salt with a wire whisk. Set aside.
In a large bowl cream butter and sugar with an electric mixer.
Add egg whites, bananas, apple sauce and vanilla, and beat at medium speed until thick.
Scrape down sides of the bowl. Add flour mixture and walnuts, then blend at low speed until combined.

Pour batter into loaf pans and bake on the center rack for 50 minutes, or until a toothpick inserted in
the center comes out clean. Let the pan cool at least 20 minutes, bread should be room temperature before slicing.
