Place a baking stone on the bottom rack of the oven and preheat to 425°F (220°C) for at least 20 minutes before baking.
Brush the olive oil onto a 13 x 18 inch (33 x 46 cm) half sheet pan and sprinkle evenly with the finely ground semolina.
On a lightly floured surface, roll the pizza dough into a 13 x 18 inch (33 x 46 cm) rectangle. Transfer to the prepared pan and gently stretch to the edges if needed.
Spread the pizza sauce evenly over the dough, then sprinkle with the shredded mozzarella cheese.
Add toppings of choice evenly over the cheese.
Bake the pizza directly on the preheated baking stone for 20-25 minutes, until the crust is deeply golden and the cheese is bubbling.
Remove from the oven and let rest for 5 minutes before slicing into 16 pieces.
Serve while still hot with a simple green salad. Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in a 350°F (180°C) oven for 10 minutes.
