Sprinkle chops with pepper; place in a shallow roasting pan. Scatter pancetta around chops. Broil chops, about 4 minutes. Turn; add rosemary around chops, and broil for another 4 to 5 minutes. Remove chops to a plate and cover loosely. Reserve pancetta and rosemary.
In a small saucepan, whisk oil, vinegar, and garlic. Stir in tomatoes and salt and cook over low heat, about 2 minutes. Add pancetta, rosemary and any juices from roasting pan. Transfer lamb chops to serving plates, drizzle with relish and serve.
