Buy some fry light cooking spray..
Peel and chop potatoes to chip shape (or any shape you fancy)
Boil them for 5 - 10 minutes
Place on baking tray & spray with fry light
Cook for about 30 minutes & turn them a few times..
..
One thing I found is to make sure all chips are really chunky because thin ones end up really crispy and often burned!
