Preheat the oven to 350°F (175°C). Spread the coconut flakes on a small baking sheet and bake until lightly golden, about 2–3 minutes; watch closely to avoid burning. Set aside.
Preheat your grill to medium and place a grill basket on the grill.
In a medium bowl toss the cauliflower florets with 2 teaspoons melted coconut oil and season with sea salt and pepper.
Place the cauliflower in the preheated grill basket and grill, stirring occasionally, until tender and slightly charred, about 10–15 minutes. Remove and keep covered to stay warm.
Arrange the plantain slices in a single layer on a plate. Brush both sides with about 1/2 teaspoon of the remaining melted coconut oil and sprinkle half of the 3 teaspoons coconut sugar over one side; flip and repeat on the other side. Set aside.
In a small bowl combine the ground cumin, cayenne pepper, the remaining 2 teaspoons coconut sugar, and a pinch of salt and pepper. Pat the chicken breasts dry and rub the spice blend evenly over them.
Grill the chicken over medium heat until cooked through and no longer pink in the center, about 4–5 minutes per side. Transfer to a plate, cover, and let rest for 5 minutes.
Grill the prepared plantain slices in the grill basket in a single layer (work in batches if needed). Flip immediately after placing them so both sides get charred; they cook quickly and should be slightly crispy and browned. Remove and keep warm.
Place the grilled cauliflower and chopped cilantro into a food processor and pulse until the mixture reaches a rice-like texture. Stir in the toasted coconut flakes.
Divide the cauliflower rice between two bowls. Top each with grilled plantains, mashed avocado, and sliced or shredded grilled chicken.
Drizzle 1/2 tablespoon honey over each bowl and serve immediately.
