Preheat the oven to 350 F/180 C/ gas mark 4. Line a large baking sheet with parchment paper and spread the kale over the top. Season lightly and drizzle over 1 tablespoon of the oil. Rub the kale with your hands until it's evenly coated in the oil, then spread over the baking sheet again (the leaves shouldn't overlap one another) and bake for 7 minutes. Remove from the oven and leave to cool for a few minutes.
Combine the kale with the other ingredients, including remaining 1 tablespoon of oil, season to taste and puree until smooth and creamy.
Cover and chill for 30 minutes before serving if possible.
To serve scatter finely chopped chillies or chives over the top, drizzle with a little oil (vegetable or olive) and enjoy with breadsticks, veggie sticks or nachos. Keep covered and refrigerated.
