"[Photograph: Yvonne Ruperti] Notes: Don't skip the cucumber salting step and use Greek yogurt for a thick and creamy tzatziki sauce. If Greek yogurt is unavailable, let regular yogurt drain in a fine mesh strainer lined with cheesecloth set over a bowl or the sink until thick and creamy, about 1 hour. Once you've marinated the chicken, discard the marinade. Whether using an outdoor grill or grill pan, brush the grates or pan lightly with vegetable oil before cooking chicken.
