Roll dough. Mark 15 slits for slicing.
Repeat with remaining dough.
Bake for an hour and a half at 350 degrees Fahrenheit.
Meanwhile, prepare the sauce. Process celery, carrots, and onions. Sautee in liberal amount of oil for one and a half hours, stirring occasionally. (Sauteed vegetables may be prepared ahead of time and frozen.)
Defrost vegetables and add remaining sauce ingredients. Bring to a boil, reduce heat, and cook for half an hour. Discard green pepper.
