Press each piece of bread until it's completely flat (Put the slices in-between two pieces of wax paper and use a rolling pin.)
Spread the hazelnut spread on one side of the flattened bread.
Then roll up each piece.
Add a little bit of butter to a frying pan.
Once the butter is melted, cover the outside of each roll and cook on all sides. (You will have to turn them.)
Once all the rolls are cooked, add a little bit of water to the strawberry preserve and stir until combined.
Drizzle the strawberry sauce over each roll and sprinkle with powdered sugar.
