Summer is the season for tomatoes and basil! But with pesto usually off-limits for people with food allergies—it traditionally contains tree nuts and dairy—I set about creating an allergen-free version of the original. The sweet and tangy roasted cherry tomatoes are the perfect compliment to the earthy flavor of the basil and the smokiness of the grilled chicken. Upon tasting this recipe, my 4 1/2 year-old son, Lennon (who has food allergies) even asked, "Can I have this pasta for lunch every day?" There is no greater compliment.
