In the bowl of a stand mixer fitted with a dough hook, Whisk the yeast and sugar into warm water and allow to stand for 5 minutes until frothy. Add the flour, salt and olive oil then allow to knead for a few minutes until the dough is soft, smooth and only slightly tacky. If the dough is very sticky, add a little bit of flour and knead in.
Transfer the dough to an oiled bowl, cover with plastic and allow to rise for at least 1 hour. I usually make the dough a few hours before cooking.
Mix the tomato passata/puree with oregano, a pinch of salt and sugar.
Preheat the oven to 200°C/390°F.
Add a few tablespoons of olive oil into the bottom of a sheetpan. Transfer the dough to the pan and gently press into the corners.
If the dough doesn't want to stretch all the way, leave it for 10 minutes and continue. It will relax enough for you to get it all the way to the edges.
Top the dough with sauce, low moisture mozzarella and then salami.
Bake the pizza in a preheated oven for 25-30 minutes or until the cheese has melted and the crust is golden brown and crisp.
Carefully lift the sides of the pizza to make sure the bottom is also golden.
Remove from the oven, allow to rest for 5 minutes then slice and serve.
