Place 1 cup of mozzarella cheese into the microwave safe bowl and heat for 90 seconds.
Add the egg and almond flour, and mix with a fork. Roll out between two sheets of baking paper to make a slightly thick square sheet of cheese
Cook for 10 mins at 180c (355f)
Remove from oven and allow to cool (I cooled it quickly by putting the baking paper back on top and rubbing the surface with ice blocks)
Mix the vegemite with the cream cheese until it becomes a consistent paste. Spread over the cooled cheese from the oven, and sprinkle with the remiaining mozzarella cheese
Lift one edge of the cheese base and roll up. Slice into 6 peices and place them horizontally on the baking pan. Cook for another 2-5 mins in the oven just so that the cheese melts inside, but the base remains structually intact.
