Ceviche
Ceviche is a popular Latin American meal that is served all throughout the continent. It's commonly cooked using white raw fish or camarones (prawns) taken off the coast of El Salvador. Because the fish is not fried but just marinated in lemon juice and chili, this is one of the healthiest Salvadorian dishes. The lemon juice "cooks" the fish, though we can't call it frying because there's no heat involved; it's more like denaturalization.
Finely chopped garlic, onion, tomato, cilantro, parsley, and chilli are common ingredients in ceviche. You can also include other ingredients, such as mango. Toss in the chili sauce, olive oil, and season with salt and pepper to taste.
Instead of the traditional Mexican tostadas, banana chips are frequently offered with ceviche. Ceviche can be found on the menus of most seaside eateries in La Libertad and its environs.
