Rwandan food is neither spicy nor hot. People eat simple meals made with locally grown ingredients. The Rwandan diet consists mainly of sweet potatoes, beans, corn, peas, millet, plantains, cassava, and fruit. The potato is now very popular, thought to have been introduced by German colonists. In urban areas meat is more plentiful. The most popular meats are beef and chicken. People who live near lakes may catch and eat fish. Tilapia and sambaza are raised on fish farms and are popular choices. A traditional breakfast consists of sweet potatoes and porridge. Lunch and dinner may consist of boiled beans, bananas, sweet potatoes or cassava. Umutsima (a dish of cassava and corn), isombe (cassava leaves with Eggplant and spinach) and mizuzu (fried plantains) are common dishes.
