Roy teaches Jon his unique preparations for a selection of Italian dishes, including artichoke salad, lasagna, and (of course) spaghetti and meatballs.

James Beard Award-winning chef Jessica Largey welcomes Roy and Jon to help cook up her unique takes on pork meatballs, grilled cabbage and roast duck.
