Whisk egg whites, milk, vanilla and sweetener/sugar until combined.

Roll bread flat with a small rolling pin. Place banana halves into each bread slice and roll them up.

Dip the sides of the rolls quickly into the egg wash (Don't soak them too much...just enough to coat).

Pan fry on a non stick pan, turning on each side until golden brown and cooked through all over.

Serve with maple syrup, yoghurt, ice cream, icing sugar etc!
