Put the flour into a large mixing bowl. Add the yeast to one side and the salt on the other.
Make a hole in the middle and add the oil, then gradually stir in the water until you get a sticky dough.
Sprinkle some flour on a surface and transfer the dough onto it. Knead until its lost its stickiness and feels soft - about 10 mins.
Put it back into a clean bowl covered with cling film or a tea-towel and leave for about an hour. It should rise to about double its size. Preheat the oven to 200C.
Oil an oven tin (about 35x25 cm, 12x8") well and spread over the dough. Push in the olives and make dimples in with your fingers elsewhere.
Bake in the oven until golden brown - about 20 mins. Sprinkle the your herbs, oil, salt - and serve in delicious chunky slices.
