Sandwiches

My favourite food is sandwiches. They consist of two slices of wheat bread with butter, and you can put some slices of cheese or sausages between them. Sometimes I add some vegetables. This may be a cucumber or lettuce. My brother also likes sandwiches, but she doesn’t like butter, so she makes her sandwiches without butter.

Бутерброды

Моя любимая еда — бутерброды. Они состоят из двух кусочков пшеничного хлеба с маслом, также можно положить ломтики сыра или колбасы между ними. Иногда я добавляю овощи. Это может быть огурец или салат. Моя сестра тоже любит бутерброды, но ей не нравится масло, поэтому она делает свои бутерброды без масла.
