In a mixing bowl, combine flour, yeast, and salt. Add warm water and olive oil, then mix until a dough forms.

Knead the dough on a floured surface for about 5 minutes until smooth. Let it rise for 1 hour.

Preheat the oven to 475°F (245°C). Roll out the dough on a floured surface to your desired thickness.

Spread tomato sauce over the dough, then sprinkle with mozzarella cheese, sardines, oregano, and black pepper.

Transfer the pizza to a pizza stone and bake for 12-15 minutes until the crust is golden and cheese is bubbly.

Remove from the oven, slice, and serve hot.
