This was delicious and so easy to put together on a busy weeknight. Our grill gets very hot so next time I'll reduce the cooking time to 20 minutes. We loved it and will definitely make it again!
Very nice. . .Great way to cook chicken, keeping it super moist! I pounded my chicken breasts for even cooking, then marinated them for about 3 hours in an Italian dressing. I used a mixture of zucchini and yellow squash; I subbed shallots for the scallions. Will definitely make again. Depending on how salty your pesto is, you may want to top it off (after cooking) with a pinch of salt and a sprinkle of parmesean cheese. Thanks for posting!
