Pre heat oven to 160/140 fan or gas mark 3.

Thinly slice the vegatables (Skin can be included) with a mandolin or peeler and try to get as wide and thin as you can.

Place sliced vegatables into a bowl and coat with oil evenly

Place vegatables on as many baking trays as necessary in a single layer. I use 3-4 trays.

Place in oven and bake for 25-30 minutes until they are crisp and lightly browned.

Store in an airtight container to keep fresh.
