Place a cooking stone or an overturned baking pan in the oven to become hot.
Place the pizza crust in the oven using a cooking shovel. Sprinkle a little flour on the shovel and spread the dough. Fold the edges, make a few holes with a fork and transfer the dough into the oven to bake, on the cooking stone at 285oC, for approx. 5 min until baked.
Once it is baked, place it on a wooden surface so as to maintain its freshness until it cools down a little.
Cut the onions in wedges and place them in a saucepan with 1 tbsp olive oil and the black sugar, to caramelize.
In a blender, add the feta cheese, mozzarella, mascarpone, pepper, remaining olive oil, and beat to a pulp.
Spread the pulp over the dough.
Cut the smoked pork in small cubes and spread them all over the dough; add the caramelized onions, thyme, and mozzarella cut in pieces by hand.
Bake for another 5 min. Sprinkle with a little arugula and serve.
