The recipe for this dish is from " High Flavor Low Labor" by J.M. Hirsh . It made for a quick, refreshingly delicious lunch. Mozzarella was added (or substituted in place of the parmigiano). It was the perfect after farmer's market lunch. The only thing I would change is the balsamic vinegar in the pesto. (Hirsh adds it and I would not.) The balsamic vinegar links to (at least in part) his philosophy for meal preparation in our too much to do, to little time world. Balsamic vinegar packs a punch in terms of flavor but fresh pesto made a day ahead is just as flavorful. And, that's how I would make this dish next time.
