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.
Fasting and abstinence in the Catholic Church
Because of this, some Catholic parishes in the United States sponsor a fish fry during Lent. In predominantly Roman Catholic areas, restaurants may adjust their menus during Lent by adding seafood items to the menu in an attempt to appeal to Roman Catholics. However, the same USCCB website says that:While fish, lobster and other shellfish are not considered meat and can be consumed on days of abstinence, indulging in the lavish buffet at your favorite seafood place sort of misses the point. Abstaining from meat and other indulgences during Lent is a penitential practice.
