In a large mixing bowl, combine flour, salt, sugar, and yeast.
Add olive oil and warm water, then mix until a dough forms.
Knead the dough on a floured surface for about 10 minutes until it's smooth and elastic.
Place the dough in a greased bowl, cover with a damp cloth, and let it rise in a warm place for about 1 hour or until doubled in size.
Preheat the oven to 220°C (425°F).
Punch down the risen dough and transfer it to a greased baking sheet, gently stretching it to fit.
Press your fingertips into the dough to create dimples.
Add toppings of choice, pressing them lightly into the dough.
Drizzle with olive oil and sprinkle with sea salt.
Bake for 20-25 minutes or until golden brown.
Allow to cool slightly before slicing and serving.
