Vegetable Crisps - Help!

[spagblog]

Hi, I tried to make vegetable crisps tonight and mucked up in a big way...smoke detectors accompanying my mad flapping of arms.
How do you make them?
I used a peeler to slice up butternut squash and carrot, sprayed them with oil and laid them on a baking tray, and stuck them in an oven - heres where I definitely went wrong - on gas mark 8.
LOL
Please can someone give me a dummy's guide to making vegetable crisps?

try cooking them slower on about gas mark 4/5 and not for very long as if they are thin they will burn quickly.

I like parsnip and beetroot ones too.

Excellent!
Blimey the recipe that I saw online said 50mins for cooking!
No wonder I was left with charcoal.
I will try them later
