1 ½poundsboneless, skinless chicken breasts or thighs
Tzatziki Sauce:
1mediumEnglish/seedless cucumber
1 ½cupsplain Greek yogurt (extra thick - see note)
1tablespoonsfresh lemon juice
1tablespoonolive oil
1 to 2teaspoonsfinely minced garlic (or 1/2 teaspoon garlic powder)
Pinch salt and pepper
Flatbread + Toppings:
6piecesflatbread or pita bread
Crumbled feta cheese, chopped tomatoes, lettuce, olives, red onions, etc.
Instructions
For the chicken, whisk together all the marinade ingredients. Place the chicken in a shallow dish or ziploc bag. Pour the marinade over the chicken and refrigerate for 1 to 2 hours or up to 4 hours.
For the tzatziki, shred the cucumber on the small holes of a box grater. Wrap the shredded cucumber in a clean kitchen towel and wring out excess liquid until the cucumber is very dry. You should have about 1/2 cup shredded cucumber.
Stir together all the tzatziki ingredients. Season to taste with additional salt and pepper, if needed. Refrigerate until ready to serve.
Preheat an outdoor grill, indoor grill pan, or oven broiler to medium or medium-high heat. Cook the chicken for 4-5 minutes each side until the chicken is cooked through and an instant-read thermometer reads 165 degrees F inserted at the thickest part. Tent the chicken with foil and let rest for 5-10 minutes.
To serve, slice the chicken and serve in flatbread or pita bread with tzatziki sauce, feta cheese, and other toppings, as desired.
Notes
Yogurt for Tzatziki: use extra-thick plain Greek yogurt for the tzatziki so it isn't runny. If the yogurt you are using has extra whey on top when opening the container, drain that off before using. Chicken: the yogurt and lemon juice help tenderize the chicken - but if the chicken marinates too long, it can develop an "off" texture because of those acidic ingredients. For that reason, I don't recommend marinating longer than four hours (preferably sticking to the two hour mark). Also, it's preferred to use chicken breasts or chicken thighs. Chicken tenders are a bit too "fragile" for this recipe unless you only marinate for 30-45 minutes.
