In a mixing bowl, combine warm water, sugar, and yeast. Let it sit for 5 minutes until frothy.

Add flour, salt, and olive oil to the yeast mixture. 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 with plastic wrap, and let it rise in a warm place for 1 hour or until doubled in size.

Preheat the oven to 400°F (200°C).

Once risen, punch down the dough and divide it into 8 equal pieces.

Shape each piece into a small round and place on a greased baking sheet.

Dimple each focaccia with your fingers, drizzle with olive oil, and sprinkle with rosemary, sea salt, and cherry tomatoes.

Bake for 15-20 minutes or until golden brown.

Remove from oven and let cool slightly before serving.
