Preheat your grill or grill pan. Remove leaves and trim stem end of cauliflower, leaving the core intact. Place cauliflower core on cutting board and using a large knife, slice it into four 1/2" 'steaks'.
In a simmering pot of water, carefully blanch the cauliflower for 4 minutes, or until softened a bit. Brush with olive oil on both sides and grill for about 3-5 minutes on each side. Keep warm.
To make sauce: drain water from cashews. Place in a small food processor with coconut oil for 5 minutes, until a puree forms. Add milk, Sweet Sunshine Jamaican Jerk sauce, and season to taste. Blend until all ingredients are incorporated. If sauce needs to loosen up, add a splash of cool water.
To serve: Place grilled cauliflower on plate, slather on Jamaican jerk cashew cream sauce, sprinkle with crushed cashews and fresh cilantro. Serve immediately.
