I whipped these up as a snack, and they took maybe 1 minute to prepare (seriously) and then 10 minutes to cook in the oven. These are so simple i'm sure everyone has had a go at them, but for the time and effort they are well worth it (and, if you're like me and have a "crab gut" from traveling in malaysia and singapore, these are superior to potato chips). i always keep a pack of pita in the freezer, specifically for this purpose.
pita chip things
pita bread, lemon juice, some good olive oil, salt, pepper, and whatever herbs you like.
preheat oven (i crank mine to 200, but i like browned, crispy ones).
tear the pita apart on a nonstick tray, ideally rubbed with olive oil to stop them sticking, but this is optional - i'm generally too lazy.
sprinkle over some good olive oil, lemon juice (i use 1/2 a lemon per pita, can use more or less if you want), salt, pepper and whatever you like. i love garlic, coriander, and maybe some chilli or tabasco. i've been known to make 2 batches at once, and have one bunch with a savage whack of tabasco, so it ends up being a surprise, that's for sure!
the thing is that this is always evolving - you can chuck whatever you want or have handy on them. shaved parmesan is good. basically, just play around with it and do what feels right.
