In a large bowl, mix warm water, yeast, and sugar. Let it sit for about 5 minutes until bubbly.

Stir in flour and salt until combined. Knead on a floured surface for about 10 minutes until smooth and elastic.

Place the dough in a greased bowl, cover with a cloth, and let it rise for 1 hour or until doubled in size.

Preheat your oven to 400°F (200°C). Punch down the dough, then divide it into small balls. Flatten each ball into a mini round about ½ inch thick.

Transfer the rounds onto a greased baking sheet and use your fingers to create dimples all over the tops.

Drizzle olive oil over each dimpled round and sprinkle with sea salt and fresh herbs like rosemary or thyme.

Bake in your preheated oven for 15-20 minutes until golden brown and puffed up.

Once cooled slightly, slice each focaccia round in half and fill with your favorite Italian sandwich ingredients.
