First make the kebab masala :
Preheat the oven to 100°C
Sprinkle the dried fenugreek onto a foil-lined baking sheet and bake for 20 minutes
Allow to cool completely
Add all the ingredients to a spice grinder and ground together then decant into an airtight container or jar
Store in a cool, dark cupboard
Preheat the oven to 200°C and roast the cauliflower for about 30 minutes until cooked through (no need to season or drizzle with oil)
While the cauliflower roasts, toast all the seeds in a hot dry frying pan for 2 minutes until fragrant
Crush them in a pestle and mortar, then set aside
Put the crushed spices in a large bowl with the melted ghee, spring onions, coriander and chillies
Put the cauliflower into the bowl with the spices and gently toss until well coated
Add the sea salt, lime juice and kebab masala, adjusting them to taste, then serve.
