Prepare the mushroom truffle salsa:

• Clean the mushrooms and cut them into slices.
• Add the olive oil to a large pan or saucepan. Sauté the onion, garlic and add the mushrooms and wine.
• Add salt, pepper, thyme, and let them simmer with the lid on for about 15-20 minutes.
• Move the seasoned mushrooms into the food processor and mix until a fine paste is formed. Add the truffle oil and then move the whole composition into a jar.
• Meanwhile, prepare the pizza.
• Grease the pan with about a tablespoon of olive oil.
• Lay the top over the pan and grease it with another spoonful of olive oil.
• Heat the oven to 250 C.
• Using a mandolin or food processor, slice the potatoes thinly.
• Put the potatoes in a bowl, pour 3 tablespoons of olive oil, salt and pepper over the potato slices. Mix the potatoes in the oil so that all the slices are coated.
• Arrange the potato slices over the pizza crust, slightly overlapping the slices until the entire crust is covered.
• Sprinkle with a little more oil and even it out with a brush over the entire surface of the potato layer.
• Put the pizza in the hot oven and bake for 10-13 minutes, until the potatoes start to brown.
• You can move the pizza to the upper grill, for another 3-4 minutes and let the grill function, to make a golden crust. Sprinkle with the mixture of Italian herbs.
• Serve hot pizza with truffle sauce over, optional.
