I love, love, love to BBQ. In Summer I BBQ at least once a week, usually. So tonight we BBQ'd burgers and hot dogs. After I am done cooking I always through some frozen chicken breast on and grill them up. Yes, it takes a bit longer for me to sit outside and grill the chicken. However, it saves time later when I need pre-cooked chicken and I don't want canned. Plus, it is way cheaper than buying cooked grilled chicken from the store.
Let the chicken cool after removing from the grill. Place it in an air tight container (I use ziploc bags) and either refrigerate it or freeze it for later use.
So my hint for all your BBQ's this Spring and Summer....Grilled Chicken! Try it, I promise you will be happy you did.
