Wash the cauliflower, bell pepper, and zucchini, and chop them into bite-sized chunks. Peel the onion, garlic, and ginger. Dice the onion, mince the garlic, and grate the ginger.
Heat the coconut oil in a large pot or wok over medium-high heat. Add the diced onion and sauté for 2-3 minutes until softened. Then, add the minced garlic, grated ginger, and spices. Sauté for an additional minute, stirring frequently.
Now, pour the coconut milk in, stir to combine, and bring to a light simmer.
Add the cauliflower and stir well to coat. Then, turn down the heat to medium, put on a lid, and cook for 10 minutes.
Stir in the zucchini and bell pepper and let simmer for another 10 minutes until the vegetables are tender. Season the curry with salt and pepper to taste, let rest, and serve.
