Boil the giblets in salted water until very tender.
Reserve this liquid (giblet broth)
for cooking the rice (adding more water or chicken broth if necessary).
Use a food processor to finely chop giblets.
In a heavy, deep skillet, cook pan sausage on low heat, and as soon as fat begins to cook out, add onion, bell pepper, celery and garlic.
Continue cooking on low heat, stirring occasionally, until all vegetables are soft.
Add cooked rice, giblets, green onion tops, parsley, pepper and seasonings. Stir or toss together gently. If possible, add some drippings from the fowl or meat entrée you are serving. Do not let green onion tops and parsley become scorched.
