Turn your oven on very low, no more than 50°C.  Mix the flour and yeast together and gradually add the warm water mixing all the time until you have a good dough.  Knead until fairly smooth and place in an oiled baking tin or two and flatten out to fill tin (this makes lovely flattish bread a bit like pizza if well spread out). 

Place into the oven and prepare the topping: mix the oil with the herbs, garlic and salt and then spread over the bread.  Turn the oven up to 190°C - the bread will continue rising as the heat increases - and bake for about 25 minutes.

You can experiment with different toppings: add a tablespoon of tomato puree for a pizza style bread - sliced onions add flavour. Sprinklings of poppy or sesame seeds go well too.
