The breakfast in Istanbul is pretty elaborate. I'd like to live there if I'm eating, but not if I have to do the cooking.
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.
Rice - in a rice cooker with timer, so just needs scooped
Natto - from a package
Pumpkin - been made already, prolly leftover from previous night's dinner
Cucumbers - same (those are not fresh, they are in a vinegary sauce)
Eggs -take 5 min, wife makes them every morning
Miso soup - leftover from previous night's dinner
Salmon - leftover from previous night's dinner, or from little "bento sized" frozen packaged & microwaved
The "real" meal is elaborate, but as you can see from above, a lot of it is left over from last night or night before, constantly mixed in for variety
These days, my older girl settles for toast :-)
