Patates Tiganites (Πατάτες Τηγανιτές) are fried potatoes, and within the Greek pita they are a structural component rather than a side dish. The model is blunt about their role: they are essential inside the pita for the authentic Greek style of wrap. Treating them honestly means describing what they do to a souvlaki or gyro when they ride along inside it, not pretending they are a sandwich. Outside the wrap they are simply chips; inside it they change the eating experience enough that a wrap without them tastes incomplete to anyone used to the real thing.
The make is ordinary frying done with intent. Potatoes are cut into batons, fried in hot oil until the outside is crisp and gold and the inside stays soft, then salted while hot and used immediately, because the whole point depends on timing. They go into the pita among the meat, sauce, onion, and tomato rather than on the plate beside it. What they contribute is texture and starch: a crunch against the soft bread and tender meat, and a neutral, oil-rich body that absorbs the tzatziki and meat juices so the wrap holds together instead of running. Good execution means the fries are fresh and still crisp when the wrap is rolled, cut thick enough to survive being wrapped without going to mush. Sloppy execution is limp, oil-soaked, or cold fries added from a holding tray, which collapse inside the pita and turn the centre of the wrap into a damp, greasy paste.
Their effect shifts with the wrap around them. In a juicy gyro they soak up fat and stretch the richness; in a leaner chicken souvlaki they add the body the meat lacks. Quantity is a judgement call, a small handful braces the wrap, while too many turn it into a potato sandwich with meat as a garnish. The tzatziki they sit against, and the wraps they complete, are full subjects that deserve their own articles rather than being crowded in here. Understood on their own, patates tiganites are the component that makes a Greek pita read as Greek: not a side that wandered in, but a deliberate layer that carries texture and binds the rest together.
