One of traditional Old Polish breakfast were scrambled eggs with addition of bacon or sausage, onion and chives. Another traditional meal was oatmeal porride, or sliced roll soaked with hot milk.
Nowadays breakfast looks a little bit different, caused by lack of time to prepare such laborious meal. Usually, by calling something breakfast, we mean yoghurt or cornflakes with milk. Sometimes, we don't have even time to prepare those meals. Usually we take an apple or some different fruit and we run out of our home.
Nowadays Polish breakfast doesn't seem to be different than in foreign countries.
