Greeks make souvlaki by marinating chunks of meat (usually pork or lamb) in oil, lemon juice, and oregano, then skewering and grilling them. Grace Parisi opts for pork shoulder because it's so tender and succulent. Instead of threading the meat onto skewers, she simply cooks it (with onions) in a grill pan until it's nicely charred, then serves it with store-bought pita and a garlicky cucumber-yogurt sauce called tzatziki.
