Piece of crusty white buttered baguette, thickly sliced bacon (grilled 'til crispy and enough to give a couple of layers), fried egg or two (solf yolk so it burst and soaks into the bread), lots of freshly ground black pepper (no salt as the bacon makes up for that) and a healthy squirt of HP sauce
However, for the ultimate, add a thick quality pork sausage (grilled then sliced lengthways) but you might need two) and some proper hog's pudding (again grilled - don't want it to be unhealthy for a snack!). Oh and a cloth to mop up the drool
