Tomato, Zucchini and Salami Pizza

Grease a large bowl with olive oil. In a small bowl, whisk the water with the yeast and let stand until foamy, about 5 minutes. In another large bowl, whisk the flour with a large pinch of salt. Make a well in the center of the flour and pour in the yeast mixture and the 1 1/2 tablespoons of olive oil. Stir with a fork until the dough just starts to come together. Turn the dough out onto a generously floured work surface and knead until very smooth, about 5 minutes. Transfer the dough to the greased bowl, cover with plastic wrap and let rise in a warm place until doubled in bulk, about 1 hour.

In a large saucepan, heat the olive oil. Add the onion and garlic and cook over moderate heat, stirring occasionally, until just softened, about 4 minutes. Add the diced tomatoes, tomato puree, crushed red pepper, sugar and basil and bring to a boil. Simmer over moderately low heat, stirring occasionally, until thickened and reduced to 2 cups, about 18 minutes. Season the sauce with salt and black pepper.

Preheat the oven to 450° for at least 30 minutes. Grease a large rimmed baking sheet. Cut the pizza dough into 2 pieces. On a lightly floured work surface, roll or stretch out 1 piece of the dough to a 12-inch round; transfer to the prepared baking sheet. Spread half of the sauce over the dough and top with half of the cheese, salami, zucchini and tomatoes. Season with salt and pepper. Bake the pizza for 15 to 18 minutes, until the crust is browned. Garnish with dried oregano and a drizzle of olive oil. Repeat with the remaining dough and toppings. Serve hot.
