The secret to this tender bread is in your hands: Don't overwork the dough--just lightly knead it.
2 cups all-purpose flour
2 cups whole-wheat flour
2 tablespoons sugar
1 teaspoon salt
1 teaspoon baking soda
3 tablespoons chilled stick margarine, cut into small pieces
1 1/3 cups low-fat buttermilk
2 egg whites
Vegetable cooking spray
How to Make It
Combine first 5 ingredients in food processor, and pulse until well-blended. With the processor on, drop margarine through food chute, and process for 10 seconds.
Combine buttermilk and egg whites; stir well. With the processor on, pour the mixture through food chute, and process for 20 seconds or until dough leaves sides of bowl and forms a ball. Turn the dough out onto a lightly floured surface, and lightly knead about 10 times.
Pat the dough into an 8-inch round cake pan coated with cooking spray, and cut a 1/4-inch-deep X in top of the dough. Bake at 375° for 45 minutes or until lightly browned. Remove bread from pan, and let cool completely on a wire rack. Cut bread into wedges.
