This recipe is for a stuffed baked red fish. It calls for sautéing vegetables like onions, bell peppers and celery with margarine and then mixing them with mushrooms, shrimp, crab meat and toasted bread to make a seafood stuffing. A whole red fish is cleaned, seasoned and stuffed with the mixture, then baked covered in a tomato-based sauce for 1 to 1.5 hours until flaky.
