Use a Japanese mandolin to get super skinny slices of vegetable for this alternative to normal crisps. A good snack to take to work.
Slice the vegetables using a Japanese mandolin.
Heat the oil in a deep-fat fryer or heavy-based saucepan to 180C/350F. (CAUTION: hot oil can be dangerous. Do not leave unattended.)
Add one type of sliced vegetables to the hot fat at a time and once browned and cooked through, remove with a slotted spoon and transfer to a plate lined with kitchen paper. Repeat with all three types of vegetable.
Sprinkle with salt to serve.
