Ethiopian cuisine
Both Ethiopian Orthodox Christians and Muslims avoid eating pork or shellfish, for religious reasons. Pork is considered to be unclean in both Ethiopian Orthodox Christianity and Islam. Many Ethiopians would abstain from eating certain meats, and would mostly eat vegetarian and vegan foods.
History of vegetarianism
In Greek-Orthodox Christianity (Greece, Cyprus, Russia, Serbia and other Orthodox countries), adherents eat a diet completely free of animal products for fasting periods (except for honey) as well as all types of oil and alcohol, during a strict fasting period. The Ethiopian Orthodox Church prescribes a number of fasting (tsom, Ge'ez: ጾም ṣōm, excluding any kind of animal products, including dairy products and eggs) periods, including Wednesdays, Fridays, and the entire Lenten season, so Ethiopian cuisine contains many dishes that are vegan.
