Preheat the oven to 400°. Place the 1T of coconut oil, if using, onto a baking sheet and place in the oven for a few seconds until it liquifies.

Cut cauliflower into large chunks. Toss onto baking sheet and coat with coconut oil. Sprinkle coriander, sea salt and pepper on top and place in the oven.

Roast until very browned on top & bottom, about 30 minutes.

Remove from the oven, top with the chilis and cilantro sprigs. Squeeze lime on top and check for taste. Add more lime and/or salt as needed. Serve.
