Preheat oven (electric cooker: 200 °C/circulating air: 175 °C/gas: see manufacturer). Line two baking trays with baking paper. Coarsely grate parmesan. Sprinkle 4 circles (each approx. 8 cm Ø) on each baking tray made of parmesan.
Bake in the oven for 7-10 minutes until the parmesan has melted.
Allow the parmesan circles to cool only briefly so that they can still be bent up at the sides to form rolls. Then let them cool down completely.
Wash the dill and chop finely. Mix mustard, honey and dill. Wash the rocket, shake dry and chop finely. Put 1 slice of salmon and rocket into each parmesan roll. Add honey-mustard sauce.
