Tasted delicous but was way too much work. I would have marinated the chicken in a greek pre-made marinade and bought tzatziki sauce. Definately bbq the chicken.
These were excellent, especially right off the charcoal grill!! Felt like I was eating them right from the restaurant. I only got a chance to marinade for a short time and it still tasted wonderful. My only comment is that there was too much Tzatziki sauce for the amount of chicken we made. We actually got about 6 gyros out of this recipe, maybe our pita bread was smaller. For that amount of chicken, next time I'd probably make a half a cup of yogurt so there wasn't so much left over. Oh, and we didn't do the aluminum foil thing either, it wasn't that messy. We also topped ours with lettuce and green peppers just because we had some. VERY GOOD!!
