Prepare artichokes for cooking as directed below; set aside.
In large bowl, combine bread crumbs, cheese, parsley, 2 cloves garlic, salt and pepper. Drizzle with 1/2 cup Olive Oil; toss just until moistened. Gently stuff bread crumb mixture between artichoke leaves.
In 12-quart nonaluminum saucepot, heat remaining 1/4 cup Olive Oil. Add remaining garlic, then artichokes. Cook 1 minute. Gently pour broth around artichokes. Bring to a boil over medium heat. Reduce heat to low and simmer covered, basting occasionally if desired, 2 hours or until leaves are tender and pull out easily.
TO PREPARE ARTICHOKES FOR COOKING: Wash artichokes in cold water; drain. With a large knife, cut stem close to base. Cut off 1/2 inch of top. Remove any discolored lower leaves. If desired, with scissors, cut off sharp leaf tips.
*For best flavor and texture, make the fresh bread crumbs using crusty Italian bread.
