Spread Nutella on one side of each bread slice. Cut the strawberries into thin slices, and then place them over the Nutella on ONE of the bread slices. Place one bread slice on top of the other, so that the strawberries are surrounded by Nutella.
Add the eggs, milk, and spices to a large container, and mix thoroughly. Place the sandwich into the mixture, allowing each side to soak for about one minute.
Now heat a bit of butter in a pan and cook until both sides of the sandwich are golden brown.
