I am a crisp addict! Well was..ive done really well to avoid buying a bag everytime i spot a shop lol.. I have discovered home made syn free crisps!! I think they are only syn free on EE though?
Basically thinly slice potatoes
Spray a plate with fry lite and place thin slices around the plate - not over lapping
Sprinkle the potatoes with salt
Spray again with fry lite
Cook in microwave for around 4mins, maybe less if you have a high watt micro, just keep and eye on them! when they change colour and seem more "transparent" lol then just remove off the plate and pop onto a wire rack or clean tray to cool off and crisp up!
I suppose you could try experimenting with flavours too like sprinkling a chicken oxo cube on them or ground rosemary just to change things up a bit??
