I found this recipe for Pesto Chicken Packets in my trusty Betty Crocker Cookbook. It looked super easy (easy to prep while sitting at a picnic table in the middle of the woods) and delicious, too. The recipe only requires four things: chicken, tomatoes, zucchini and basil (I made my own pesto).
The chicken was super tasty and, like I thought it would be, easy to make. It took about 20 minutes over a pretty hot fire to cook. I think each packet could have used a bit more pesto (the recipe says it makes four servings; I made six by adding more chicken and a bit more zucchini and tomato).
I think it's a great starter recipe--you could add more vegetables, different vegetables or even put a different sauce on top. We served ours with a rice, black bean and corn salad. It was a hit! (And for the record, Betty Crocker is/was not a real person :)).
