Wash and dry the herbs, then chop finely. Alternatively, use freeze-dried herbs. Knead all ingredients together for 1-2 minutes until fully combined.
Line a baking sheet with parchment paper. Shape the dough into about 12 small balls, then press each one flat. Place on the prepared sheet.
Sprinkle with coarse sea salt. Bake at 180°C (356°F) in a fan oven, or 200°C (392°F) in a conventional oven, for 20-25 minutes until the edges turn slightly golden brown.
