Mix the egg, spices and sweetener in a shallow dish.
Cut the crusts off the bread and evenly spread the chocolate spread over one slice. Pop the second slice on top to create a sandwich.
Put the "sandwich" into the egg mixture. Leave to soak up the egg and spices for a minute, then turn and leave for another minute to soak on the opposite side.
Place a non-stick frying pan on a medium heat and spray with low calorie cooking spray. Carefully place the French Toast into the frying pan and fry on each side for about 3 minutes until golden and crisp.
