For garnish: sliced green onions, toasted white and black sesame seeds, sea salt
Preheat the oven to 425 degrees.
Cut the leaves and stem off the cauliflower so that it sits flat.
In a small bowl mix together the sesame and grape seed oils, the miso paste, Chinese chili garlic sauce and the ginger. Using your hands rub the mix over the cauliflower, making sure you get it everywhere, even the bottom.
Roast the cauliflower in the oven for 44-50 minutes, or until it is soft and brown. Remove the cauliflower from the oven and season with sea salt and sprinkle the green onions and toasted sesame seeds over before serving.
