These are so good. I made a batch intending to share them with husband when he got home. They didn't last untill evening I'm afraid.
I had been given a variety of coloured of beets by my mother in law, a dedicated gardener, that then sat in the bottom of my fridge getting wrinkly. Any root veg would work though; potatoes, sweet potatoes, beets, carrots. It makes great use of any odd spare veg.
I peeled them and sliced them thinly using my mandoline, managing not to lose any digits. Patted them dry, and sprinkled with salt, then laid them on a plate (NOT touching!) and microwaved for 3 mins full power, turn them over then a further 3 half power. Remove the crispy ones, and keep zapping for 30 sec intervals untill they're all done. Allow to cool, then either gobble them all up and deny their existence, or keep them to share.
Incidentally I first used some of that bake o glide as a liner, thinking myself v clever, but one of them actually caught fire. Bad idea.
