Kenyans generally have three meals in a day – breakfast in the morning (kiamsha kinywa), lunch in the afternoon (chakula cha mchana) and supper in the evening (chakula cha jioni or known simply as "chajio"). In between, they have the 10 o'clock tea (chai ya saa nne) and 4 pm tea (chai ya saa kumi). Breakfast is usually tea or porridge with bread, chapati, mahamri, boiled sweet potatoes or yams. Ugali with vegetables, sour milk, meat, fish or any other stew is generally eaten by much of the population for lunch or supper. Regional variations and dishes also exist.
