To make the cardamom yogurt sauce: In a small bowl, combine the yogurt, lime juice, cardamom, a generous pinch of kosher salt and freshly ground black pepper. Chill until ready to serve.
To make the cauliflower fried rice: In a large skillet, heat the coconut oil over medium heat. Add the onion, cauliflower, a pinch of kosher salt, and some freshly ground black pepper. Cook until the cauliflower is lightly browned, about 5 minutes. Add the cashews and chickpeas and cook until both are lightly browned, 5 minutes more.
Add the curry powder, turmeric, red pepper flakes (if using), and green onions. Stir and cook until the spices are fragrant, about 30 seconds. Reduce the heat and add ½ cup [125 ml] of the coconut milk. Add the lime juice, golden raisins, and another pinch of kosher salt. Add the cooked rice and stir to incorporate, breaking up clumps with a wooden spoon. Add the remaining ¼ cup [60 ml] coconut milk and stir in the coriander. Season to taste.
SERVING: Serve in individual bowls, topped with the cardamom yogurt sauce.
STORAGE: Store leftover cauliflower fried rice in an airtight container in the refrigerator for up to two days.
