This is true end-of-summer fare. A batch of pesto from the basil that’s growing gangly in the garden. (Try our zippy Asian Pesto, Basil-Mint Pesto or Spicy Sage and Parsley Pesto.) A spatchcocked (butterflied) chicken cooked (relatively) quickly on the grill, since the days are shorter now. Which is good. I like saying goodbye to a season with a taste of all I love about it — and this grilled chicken recipe has it.
