Dice up the stems of the cilantro bunch and set aside. In a large soup pot saute the onions in the coconut oil. When the onions start to turn brown, add the garlic and the cilantro stems and saute for another 2-3 onions. Add the tomatoes, cumin, salt and pepper, mix well and cook for another 2-3 minutes. Add the coconut milk and bring to a simmer. Add the seafood and cook for another 3-5 minutes or until the seafood is done. Serve with the cilantro leaves on top as a garnish. Enjoy!
