Souvlaki Kotopoulo (Σουβλάκι Κοτόπουλο) is the chicken version of the skewered Greek street staple: cubes of chicken breast threaded onto a stick and grilled over coals. The word souvlaki points to the skewer itself, the souvla, and the kalamaki, the little reed-thin stick the meat rides on. This is the leaner cousin in the souvlaki family, and the meat choice changes everything downstream: chicken breast has almost no fat to render, so the grilling and the marinade carry the whole result.
Build starts with the cut. Breast is dense and dries out fast, so the cubes should be uniform, on the larger side, and marinated long enough to matter, typically olive oil, lemon, oregano, garlic, salt. The oil insulates against the dry heat and the acid loosens the surface; skip it and the chicken grills to chalk. Threading is its own discipline. Cubes packed too tight steam against each other and stay pale; spaced with a hair of air between them, each face gets direct fire. Good execution is char on the corners, a faint pink-free juice, and meat that still bends rather than snaps. Sloppy execution is the giveaway of bone-dry skewers held too long on the grill or cooked from cold, gray instead of golden, with that cottony pull that no amount of tzatziki can rescue. The skewer should come off the coals and rest a beat before it is pulled or served, not torn apart steaming.
On its own the kalamaki is eaten straight off the stick, often with a wedge of lemon, oregano, and nothing else, which is why the marinade and the char have to be good enough to stand alone. From there it scales: the same chicken cubes wrapped into a pita with tzatziki, tomato, onion and fries become a portable handheld, and that pita format is distinct enough that it deserves its own article rather than being crowded in here. Mixed-meat skewers and the beef version sit beside it on the same grill, each with its own behavior under heat. What stays constant across all of them is the logic of the souvlatzidiko grill: small skewers, fast fire, finished to order, never held warm in a tray.
