The breakfast is what we call in Southern England full English Breakfast what the Scots call it I do not know.
Regarding sausage and mash with onion gravy. We use normal English sausages just a regular herby sausage and the gravy is usually made from stock cubes or powder and cooked onion which if you have fried the sausages would have been fried first with them to give more flavour if you have grilled (broiled) the sausages then the onions would just have been fried gently in a frying pan with a little oil until soft and then added to the gravy.
Hope that made sense.

Full English Breakfast is exactly what he told me to look up.
It does look yummy! When he told me to look it up, I saw the beautifully done plates.
