With double-meat sandwiches, it is important to tread carefully. So for this indulgent combination of marinated chicken and cured meat, I gathered exceptionally gourmet ingredients: Point Reyes blue cheese, capocolla (aka coppa) from Chris Cosentino's Boccalone deli, and organic chicken thighs. Since I was piling meat upon meat with creamy cheese, I made extra-small sandwiches using soft but firm dinner rolls.
