Loopy - mix packet of soup into thickish paste with fizzy water.
Put small blobs on greaseproof paper and microwave for 1-2 mins... This time will depend on your microwave and how many blobs you have, how thick the paste is too etc. So watch it!
Sometimes mine take a bit longer.
When they go golden browny colour take them out. Let them cool a bit and peel off- you have sorta crisps...
Don't expect it to be haute cuisine though!
3 batches to cook a whole packet (only fit 1/3 of the mix in my microwave at once).
