In a large mixing bowl, combine the sourdough discard, warm water, and olive oil. Mix until well combined.

Gradually add the flour, salt, and sugar to the bowl. Mix until a dough forms.

Flour a clean surface lightly and transfer the dough. Knead for about 5-7 minutes until smooth and elastic.

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

While the dough is rising, mix the minced garlic, chopped parsley, and optional cheese in a separate bowl.

Once the dough has risen, punch it down gently. Divide it into smaller pieces, roll each into a ball, and flatten slightly.

Place a dollop of the garlic mixture in the center of each piece, fold the dough around it, and pinch to seal. Arrange the filled pieces in a greased baking pan.

Cover the pan lightly and let the assembled balls rise again for about 30 minutes.

Preheat your oven to 375°F (190°C).

Bake the bread for 25-30 minutes or until golden and crisp on top.

Allow the bread to cool slightly before serving. Enjoy it warm.
