In a large pot or Dutch oven, heat coconut oil over medium heat. Add the chopped onion and sauté for 4-5 minutes until translucent. Add the minced garlic and grated ginger, cooking for an additional 1-2 minutes until fragrant.
Stir in the curry powder, turmeric, cumin, and salt, cooking for another minute to toast the spices.
Add the cauliflower florets and chickpeas to the pot, stirring to coat with the spice mixture. Pour in the vegetable broth and coconut milk, bringing the mixture to a gentle boil.
Reduce the heat to low, cover, and let it simmer for about 20 minutes, or until the cauliflower is tender.
Stir in the chopped spinach and cook for an additional 2-3 minutes, allowing it to wilt.
Serve hot, garnished with fresh cilantro and lime wedges on the side for an extra zesty touch.
