1) The first thing that will appear in your head after you will be asked about the British food is probably bacon and eggs or fish and chips. Surprisingly, it's not so, because the majority choose a breakfast of cereal or toast with tea, coffee or fruit juice. It's all because of most people in the UK don't have enough time to make the traditional English breakfast, because they hurry to their work in the morning. Both children at school and adults at work have a simple 'packed lunch' from home, which contains a sandwich, a packet of crisps, a piece of fruit and a drink. Favourite dishes for dinner with all the members of the family are spaghetti bolognaise and shepherd's pie. Very often British order takeaways, such as Indian, Chinese food or pizzas.
2) It's a traditional to get together for Sunday roast every Sunday. This is usually roast beef or lamb with potatoes, vegetables and gravy.
3) By the way, what about desserts? British desserts are all delicious. They are home-made puddings like bread and butter pudding, apple pie and trifle. There can be no meal without desserts!
