Combine onions and garlic and cook, covered, over low heat until soft, stirring frequently so they don't scorch. Add parsley, bell pepper, tomato sauce, wine, water, thyme, rosemary, salt, pepper and bay leaf and simmer, covered 1 hour. Add crab or white fish, shrimp, scallops
or clams and cook, covered, for 8-10 minutes or until scallops or clam shells open. Discard any shells that do not open.
