1- Heat up the oven to about 180*/ gas mark4. Meanwhile, thoroughly wash your kale and rip leaves into several pieces, removing any stems; large leaves work the best.

2- Lay it on a large, very lightly greased flat metal baking tray, place in the oven and leave for about 20 minutes until the leaves have gone dry and crispy, while retaining their bright green colour. Oooh! This tasty snack lasted no time in the office.
