At a holiday barbecue, it's always good to offer a chicken option for your guests who don't eat red meat. Preparing chicken for the grill is so easy. In most cases, a marinade of a few hours (or overnight) is all that's needed, along with a vigilant eye at grilling time -- and a willingness to poke the chicken with your finger -- to make sure it doesn't overcook. You can even grill most of these recipes ahead of time, which makes your life easier and leaves more room on the grill for those last-minute burgers or tofu hot dogs. Use frozen chicken breasts from your pantry, or buy a boneless, skinless turkey breast at the supermarket; then mix and match the marinades, as any of the ones for chicken will be just as good on turkey. Note: the marinades are naturally gluten-free when you use gluten-free condiments, such as tamari soy sauce. Now, get your grill on!
