Много людей в Англии едят сандвичи на ланч. Существует множество магазинов с сандвичами в Лондоне. Вы можете купить любые сорта сандвичей в этих магазинах. Вы можете взять мясной сандвич, салатный сандвич или мясной-и-салатный сандвич. Вы даже можете купить фруктовый сандвич. Каждый сандвич состоит из двух тонких ломтиков хлеба. Вы намазываете масло и кладёте мясо между двумя ломтиками. Многим иностранцам не нравятся Английские сандвичи. Им больше по душе сандвичи, которые мы зовем роллами.
