This is one of my all time favorite grilling recipes! Company worthy, for sure. A friend introduced me to the recipe via a blog post on Simply Recipes. Goes together in snap. It's not very spicy, in my opinion, just extremely flavorful. (and I'm not ordinarily a cilantro person) I've done both bone-in and boneless chicken thighs. The great thing about the chicken thighs is that it is hard to overcook them and dry them out. I love the crust that the chicken gets when you grill it and you definitely have to reserve some to top it at the table. Delicious!
