Steam or boil the cauliflower in a little water for 3-4 minutes, drain and then place onto a large flat baking tray. Add the red onion wedges and broccoli, drizzle with oil and scatter with the smoked paprika, coriander and cumin seeds, season well and roast for 15 minutes or until golden brown and lightly charred all over. Place a 26cm flan dish into the oven to warm up.
Meanwhile, beat together the eggs and crème fraîche.
Lightly oil the hot dish. Tip the roasted veg in an even layer into the disk, pour around the egg mix, season well and bake for 15 minutes or until just set.
Remove from the oven, cut into wedges and serve with rocket salad.
