Prepare the dough: Dissolve yeast and sugar in warm water. Mix with flour, salt, and olive oil. Knead 8–10 minutes and let rise 1–2 hours until doubled.
Pre-bake the crust: Roll dough, place on a greased baking sheet, brush with olive oil, bake 8–10 minutes at 425°F (220°C).
Make the tomato sauce: Sauté garlic in olive oil, add tomatoes, salt, pepper, oregano, and sugar; simmer 10–15 minutes.
Assemble the pie: Spread mozzarella on the crust, spoon tomato sauce on top, sprinkle Pecorino Romano and breadcrumbs.
Bake: 425°F (220°C) for 15–20 minutes until bubbly and golden. Cool slightly, garnish with basil, slice, and serve.
