Make dough by placing flour, yeast, EVOO, salt and water into Thermomix bowl and mix 6 sec/speed 6. Knead 2 min/Interval. Wrap tightly in Silpat mat and allow to prove until doubled.
Meanwhile place all cheeses into Thermomix bowl and mill 7-8 sec/speed 8.
Use a little of the melted butter to prepare a rectangular baking dish.
Roll dough into a large rectangle and brush with more butter.
Spread almost all of the cheese on the dough being sure to cover all the edges. Sprinkle with freshly ground pepper.
Roll into large sausage shape and then cut through using pastry scraper. Turn filling side up and arrange in baking dish next to each other so there are no gaps. Allow to rise a little.
Drizzle with remaining butter, top with remaining cheese and place in a cold oven set to 200°C for 20 minutes or until golden.
(Using a cold oven gives you a little extra rise as the oven heats up!)
SERVE HOT!
