Most people in the UK rush to work in the morning. This means they don’t have time to make the traditional English breakfast of eggs, bacon and sausages. They may have one a weekends though. During the week, they choose a breakfast of cereal or toast with tea, coffee of fruit juice. Lunch is a simple meal. Many children at school and adults at work bring a packed lunch’ from home. This is a sandwich, a packet of crisps, a piece of fruit and a drink. Dinner is a meal for the whole family. Spaghetti bolognese and shepherd’s pie, are favourites. Many British order takeaways as well! Indian, Chinese food and pizzas are all very popular.
On Sundays, the British get together for a traditional Sunday roast. This is roast beef or lamb with potatoes, vegetables and gravy.
But . . . is there anything for dessert? Homemade puddings like bread and butter pudding, apple pie and truffle are all delicious British desserts. Without them no meal us complete!
