6 - 8Greek Pita Flatbread, homemade or store-bought (recipe in separate recipe card below)
Diced Roma tomatoes, peeled and diced cucumbers, chopped Romaine lettuce, diced red onions, feta cheese, cilantro and Kalamata olives (olives optional)
To make Greek chicken:
In a mixing bowl, whisk together olive oil, lemon juice, Greek yogurt, red wine vinegar, chopped red onion, garlic, oregano, thyme, coriander and season with salt and freshly ground black pepper to taste.
Place chicken in a gallon ziploc bag, pour marinade over chicken, seal bag while pressing out excess air and transfer to refrigerator to marinate 2 - 4 hours. Remove chicken during the last 30 minutes of marinating to rest at room temperature before grilling (leave in marinade).
Brush grill grates lightly with oil and preheat grill over moderately high heat. Once hot, add chicken and grill until cooked through (internal temperature should register 165 degrees F on an instant read thermometer), rotating once halfway through cooking.
Remove from grill transfer to plate and brush chicken lightly with olive oil then cover with foil and allow to rest 10 minutes. Dice into strips.
To make tzatziki:
Place diced cucumber in a mesh strainer or colander and sprinkle with salt, toss to evenly coat then allow to rest 30 minutes at room temperature.
Rinse cucumbers and place over several layers of paper towels. Squeeze some of the liquid from cucumbers (almost as if wringing moisture from a cloth). Place cucumbers in food processor and pulse to chop to desired size.
Add in Greek yogurt, garlic, lemon juice, olive oil, red wine vinegar, parsley, and dill and season with salt and pepper to taste.
Pulse to blend (or if you want it chunky you can simply stir the other ingredients in using a bowl and spoon so the cucumbers are chopped up more). Store in refrigerator in an airtight container up to 3 days.
To assemble gyros:
Layer chicken in a row along center of pita, top with lettuce, tomatoes, cucumbers, Kalamata olives, red onion, feta, cilantro and tzatziki sauce. Wrap and serve.
*I just peeled the cucumber, sliced in half lengthwise, then used a spoon to scoop the seeds out and diced into chunks.
