Preheat the oven to 180℃. Grease a 30cm x 20cm baking dish or tin with olive oil or butter, set aside.
In a large bowl, combine all the dry ingredients. In another medium size bowl, combine the eggs, olive oil, mineral water and honey.
Make a well in the dry ingredients bowl, add the wet ingredients and combine well. Then add the herbs and most of the feta cheese.
Pour batter into the prepared baking dish. Crumble remaining feta over the top. Bake in the oven for about 30-40 minutes, or until golden brown. Check its cooked by poking a skewer or toothpick in the centre. Serve with Greek yoghurt, butter or drizzled with honey. Enjoy!
