I love my halogen oven and I make SW chips all the time. I chop my potato into chips then instead of par boiling the chips I spread them out on a plate and microwave them on full power (900w) for 2 minutes. Then I spray my halogen baking tray with Fry light, spread out the chips on the tray and spray the chips with a couple of sprays of Fry Light. Pop them on the halogen at 200 for 15 to 20 minutes.
