The exact time it will take to cook the chips in the microwave will vary depending on the power of the microwave, how 'wet' the vegetable is and how thick the slices are so be prepared to experiment a little with the first batch.

1 potato - that's it!
Slice the potato very finely using a vegetable peeler or mandolin.
Place the slices on a sheet of non stick parchment or kitchen paper and place in the microwave. Cook on high for about 2-3 minutes until golden and crisp. Allow to cool before removing from the sheet.
Season to taste.
