Look carefully. Except for the eggs, none of it needs to be cooked fresh, including the pastry. Cheeses, olives, halvah etc go from fridge to the table, back to fridge, and get restocked on the weekends...
I can only say this from experience traveling around the mediterranean, but this seems to be a pretty common breakfast.
Some olives, feta cheese, a boiled or fried egg, some sliced tomatoes and cucumber, fresh brown bread with butter and some jam or honey. Once prepared you can quickly make little sandwiches, and is quite tasty!
These meals are pretty easy to put together, when tomatoes are good my wife and I often switch off on making breakfast and can whip this up for ourselves pretty quick. It's much more enjoyable than our normal greek yogurt, granola, and fruit.
I was thinking the same thing for the Japanese breakfast. Are those foods prepared beforehand or is someone (probably the mom) waking up early to cook those?
