Tzatziki Chicken

I had about 2 cups of homemade tzatziki sauce leftover after these Kofta I made last week

so here's what I did for Tzatziki Chicken. It's much the same as shish taouk.

I took 9 skinless, bone-in chicken thighs and tossed them in the tzatziki sauce, put them in a tupperware and refrigerated them overnight. I forgot to reserve some of the sauce to serve the chicken with : (    Oh well, next time.

Preheat your BBQ to 350-375 F and grill for 35-45 minutes.

And, of course, discard any marinade remaining in the container.
This would also be great using boneless chicken breast.
