In a bowl, mix the flour, yeast, and 1/2 teaspoon sugar. Add the milk and extra virgin olive oil, and combine with a fork. (I used a stand mixer.)

Finally, add the salt. When the dough is ready, let it rise overnight in the refrigerator. In the morning, take it out and let it rise again, or you can let it rise for 3 hours covered with plastic wrap in a warm place.

Place the dough on a floured surface and roll it out with a rolling pin. Cut out circles using rings of your preferred size or a glass. Let them rise for another hour.

Line a baking sheet with parchment paper, place the dough circles on it, and top with tomato sauce, oregano, and mozzarella cheese.
