Cuisine varies by region, but a large, one-course, evening meal is common throughout the country. A typical dish is based on cocoyams, maize, cassava (manioc), millet, plantains, potatoes, rice, or yams, often pounded into dough-like fufu. This is served with a sauce, soup, or stew made from greens, groundnuts, palm oil, or other ingredients. Meat and fish are popular but expensive additions, with chicken is often reserved for special occasions. Dishes are often quite spicy, with salt, red pepper sauce, and Maggi.
