Who knew? Well, Jamie Oliver knew, and I watched his 15 minute meals thingy - and thought I would try it - excellent results. Dry poppadoms from asian supermarket - broken into pieces - spread out on a plate - bung 'em in the microwave 90 seconds later all crisp and snacky! Will do this again - and will do a raita thing too.
I have just checked the ingredients and these are also gluten free and vegan (lentil flour, rice flour, sodium bicarb, vegetable oil and water) ... so, plus points all round.
