Banana-Orange Muffins

Preheat the oven to 375 degrees F. In a bowl, combine the egg whites, brown sugar, melted margarine, bananas, and the orange juice. In a second bowl, combine the remaining dry ingredients. Stir the dry ingredients into the orange-banana mixture. Divide the batter into 12 muffin cups sprayed with a nonstick vegetable oil spray, like Pam. Bake for 20 to 25 minutes until golden and cooked through. A toothpick or knife inserted in the center of the muffin should come out clean. Cool on a wire rack.
