What is a Great Northumberland Breakfast?

I'm sure everyone has their own opinion of what ingredients make up a Great Northumberland Breakfast, but what do you think? What do you have to have on your plate before you're ready to take on the day?

We just want you to tell us about those essential ingredients which turn an ordinary breakfast into a Great Northumberland Breakfast!

Feel free to be as specific as you like. If you think bacon is essential, then great, but if you think it has to be 2 rashers of grilled thick-cut streaky bacon then that's great too!
