Preheat oven to 350. In a mixing bowl, combine turkey, cream cheese, bell peppers, onions, black pepper, and milk. Mix until well blended. Perforate rolls in twos. Then, close perforations with fingers to form rectangle. Divide turkey mixture into 4 portions. Spoon onto rectangle shaped dough. Pull 4 corners toward center and close sides by pressing together. Bake for 25 minutes.
