1. For the dough: dissolve the yeast in the water in a glass to activate it. After about ten minutes, there should be bubbles.
Pour this mixture into the flour, oil, and salt and knead. The dough is ready when it is smooth and no longer sticky. Form a ball and let it rise with a little olive oil. Cover and let it rest for at least 2 hours. It should double in size.
2. Flatten the pizza, leaving some air in the crust to create a nice shape. Drizzle with a little olive oil and sprinkle with oregano if desired.
3. Cut the mozzarella into small cubes, crumble the gorgonzola into small pieces, drain the ricotta, and grate the parmigiano reggiano.
4. Evenly distribute the small cubes of mozzarella, alternating with small pieces of gorgonzola, ricotta, and parmigiano reggiano on the dough. Bake in the oven for 20-25 minutes.
