In a shallow bowl whisk your milk and egg together.
Dip your gluten free bread into your mixture, coating it on all sides thoroughly.
Heat the oil in your frying pan.
Carefully place your slices of bread into the frying pan (together or one by one depending on the size of your frying pan). Cook on both sides until lovely, crisp and golden.
Remove the french toast from the pan and add one heaped tea spoon of Nutella onto one slice of your french toast followed by slices on banana. Place your other slice of french toast on top.
Cut your Nutella and banana french toast sandwich in half and serve up with fresh blueberries, raspberries and any leftover banana.
You might like to add a mixture of seeds and/or nuts for an extra crunch or a dollop of fromage frais to serve.
Enjoy!
