I'm all over the place when I do a cooked breakfast sometimes. I like to grill the bacon, black pudding or sausages, fry the kidneys and poach the eggs. There's pans everywhere! I spend most of the afternoon washing up. I go for a variation on the theme of: crisp grilled bacon, 2 poached eggs, fried mushrooms, buttered toast, ice-cold orange juice - literally, in that both the juice and glass have been in the freezer for about 15 mins. It's the business. I rotate the meat bit of it - sometimes highland black pudding from my local butcher, or Lee House Farm pork sausages, or fried lamb kidney.
I'm interested you said "Sunday" specifically. I have a big cooked breakfast on Sundays - every other Sunday to be precise. Hopefully not too frequent so it's a health risk, but infrequently enough to make it a big treat.
