Set oven to 400F.
Chop up the cauliflower to create florets.
Pour olive oil over cauliflower florets, then add curry, coriander and sea salt & pepper.
Mix it up, ensuring all the florets are covered, then dump them on a baking sheet.
Roast the florets in the oven for 25 to 30 minutes.
Once it has finished roasting, add cilantro, chopped pistachios and fresh lemon juice.
