Preheat waffle iron according to manufacturer's instructions.

Separate eggs, placing whites in a clean, dry bowl.

Beat egg whites until stiff peaks form.

In a separate bowl, combine flour, baking powder, milk, bran, and vanilla extract.

Gently fold the flour mixture into the beaten egg whites, being careful not to deflate the whites.

Spoon batter onto the preheated waffle iron.

Cook until golden brown and crisp.

Serve immediately with desired fruit sauces.
