The Full English Breakfast is a traditionally cooked "breakfast" that today is also served at other times during the day, like at "Brunch" - breakfast and lunch - which is a late breakfast and a early lunch and quite often eaten on the weekends by many busy city people.
The usual ingredients of a traditional full English breakfast are bacon, eggs, fried tomatoes, fried mushrooms, fried bread or toast, and sausages, usually served with a large cup of tea or a "mug" of tea. Black pudding is sometimes part of English Breakfasts in places like Scotland; as well as fried leftover mashed potatoes, often called "Porato Cakes" or "Bubble and Squeek" - a vegetable left over from the previous night that is fried with potatoes. Baked beans and hash browns are also a modern staple in many dishes.
When an English breakfast is ordered in a pub or restaurant and everything available is added to it, it is often referred to as a "Full Monty"
