Preheat oven to 180°C and line a baking sheet with paper. Set aside.
Place cheese into the Thermomix bowl and mill 5 sec/speed 10.
Lay pastry on a silpat mat and spread the ThermoMite or vegemite across evenly and quite liberally.
Sprinkle with the milled cheese and roll up lengthways into a long roll.
Use a piece of unwaxed and unminted dental floss to cut through the scrolls by pulling it under the dough and tying it across. Place cut side up on the prepared tray and brush with egg wash. Bake 25-30 minutes until golden.
Serve hot or cold.
