I'm Mehmet and I'm from Turkey.Turkish food is delicious and it's healthy,too.We eat a lot of fresh vegetables like peppers, onions and aubergines.We also eat a lot of meat,lentils,beans,yoghurt and nuts.In the summer,the weather is very hot,so we often eat light meals with lots of vegetables and fruit. My favourite dish is kebab.It's a traditional Turkish dish,and it's traditional in lots of other countries,too.You can have doner kebabs or shish kebabs.A doner kebab is meat cooked in a large block.You cut small pieces of meat from the block and put it in a piece of meat cooked on a stick.I usually put some tomates,onions,cucumber and yoghurt in the pita with my meat.Kebabs are very tasty!
