1Heat oven to 350°F. In each roll, cut a pocket from the top down to within 1/2 inch from each side, cutting almost to but not through the bottom; set aside.
2Line bacon rack or microwavable plate with microwavable paper towels; place bacon on rack. Cover with paper towel. Microwave on High 4 to 6 minutes or until bacon is crisp. Crumble bacon when it is cool enough to handle.
3In small bowl, mix bacon, olives, onions, mayonnaise and 1/2 cup of the cheese. Fill each pocket with 1 heaping tablespoon bacon mixture. On ungreased cookie sheet, place rolls; sprinkle each roll with 2 teaspoons cheese. Bake 14 to 16 minutes or until filling is hot.
