Dough: 1. In a large bowl, pour in the water, preferably warm but not hot! 2. Add the yeast, sugar, and salt, and mix well. 3. Gradually add the flour and stir (it's best if the flour is sifted beforehand). 4. Once the dough is kneaded, add the olive oil and continue kneading until it stops sticking to your fingers and the surface; add more flour if necessary. 5. Let the dough rise for 30-40 minutes.
Pizza: 1. Roll out the dough. 2. Spread with tomato puree and sprinkle with cheese. 3. Season with oregano. 4. Bake the base in a preheated oven for about 12-13 minutes. 5. Top with arugula, thin strips of prosciutto, and parmesan.
