This Mexican fish ceviche with coconut and lime is a refreshing and tangy dish that combines fresh fish with a zesty marinade of lime juice and coconut milk. The fish is marinated in the mixture, allowing the acidity of the lime juice to gently 'cook' the fish. The ceviche is then garnished with fresh herbs, diced vegetables, and a sprinkle of chili powder for added flavor and heat. This Mexican fish ceviche is perfect as an appetizer or light lunch.
