Preheat the oven to 400F.
Add all ingredients to a 9x13 casserole dish, apart from the lime and cilantro.
Mix until completely combined. Cover with a lid or foil, and bake for 1 hour, until the sweet potato is tender.
Drizzle with some coconut milk, and lime juice and garnish with fresh cilantro. Serve over rice, if desired.
