Preheat your oven to 180 degrees Celsius (350 degrees Fahrenheit).
Get your lebanese bread and lay it out on an oven tray. I like to use a pizza tray coz it has holes in it that let the air circulate. It'll go really nice and crusty then.
If you want, you could probably use pita/pide bread instead. It won't come out as crispy but it'll be a bit more substantial.
Get some olive oil and pour it into a teacup or something. This will make it easier to spread. Grab a pastry brush and brush oil all over the bread round.
Sprinkle spices all over the oiled bread round. In the picture I was only using rock salt, which is why you can't see anything. I'd've added rosemary too, but I was out :P
I have been known to use steak salt and pepper spices as well.
Basically whatever you like in spices would probably go nicely on this. And it's not like it's expensive anyway, so give it a go!
Whack it in the oven for about 15 minutes or until it feels crispy (ie. It doesn't flop when you pick it up). The oil won't dry out until you take it out of the oven, so don't wait until it doesn't look oily anymore or you'll crucify your noms.
Let it cool enough for you to pick it up. Break it up into chunks (however big you like your chips) and bung it all in a bowl.
Serve with dip/sour cream/natural yoghurt/whatever you like.
Note: With pepper seasoning, it comes out REALLY spicy. One way to take away the mouth-flame is to put grated cheese on the chip and jam the whole thing in your gob at once :)
