A main-course salad brimming with lots of vegetables and lean meat is one of my favourite ways to put a healthy meal on the dinner table. This one is zesty, with arugula and peperoncini (pickled Italian peppers) in the citrusy vinaigrette. The zucchini ribbons, which look like wide pappardelle pasta, have an appetizing, fresh texture and look beautiful on the plate. When weather permits, cook the chicken breasts on an outdoor grill.
