@NoNAND I am Greek, so... also, having homemade gyros every day is actually an incredibly cheap and balanced diet, it's what I've been doing for a while to get by with my crappy food budget lol
Gyros are traditionally thin strips of lamb on pita with tzatziki sauce (it's a savoury yogurt sauce with cucumber). They are really good. Many times souvlaki is eaten in a similar fashion, but the meat is cooked differently and is closer to a skewer.
