In a large bowl, combine the water, sugar, and yeast. Let the mixture rest for 5 minutes, or until the yeast begins to bloom.
In a small bowl whisk together the olive oil, Italian seasoning, garlic, and half of the salt.
Pour half of the oil mixture into the yeast mixture. Set the remaining oil aside.
Add the flour to the yeast mixture. Stir to combine.
Add the dough to a greased bowl and cover with a clean tea towel. Rest for 1 hour in a warm place, or until the dough has doubled in size.
Preheat the oven to 450°F.
Pour the remaining oil mixture into a 9x11-inch baking dish. Use a pastry brush to coat the bottom of the dish.
Transfer the risen dough to the prepared baking dish. Work the dough to the edges and use your fingers to create dimples in the dough.
Brush the top of the dough with 1 teaspoon of olive oil and sprinkle the remaining sea salt. Bake for 18-20 minutes, or until the top is golden brown.
