In a large bowl, combine warm water, sugar, and active dry yeast. Let sit for about 5-10 minutes until frothy.

Add the olive oil and stir to combine.

Gradually add all-purpose flour, salt, and rosemary. Mix until a dough forms.

Knead the dough on a floured surface for about 5 minutes until smooth.

Place the dough in a greased bowl, cover, and let rise in a warm place for about 1 hour or until doubled in size.

Preheat the oven to 425°F (220°C).

Punch down the dough and transfer it to a greased baking sheet. Press out to form a flat rectangle.

Dimple the surface of the dough with your fingers and drizzle with olive oil. Sprinkle with coarse sea salt and add cherry tomatoes if desired.

Let the dough rest for another 20 minutes.

Bake in the preheated oven for 20-25 minutes or until golden brown.
