Heat the oil for 2 minutes in a large, heavy saucepan over medium heat. Add the flour and, stirring constantly and slowly, make a roux the color of chocolate (see Eula Mae’s Roux). Add the ground beef, pork, and chicken gizzards and season with the salt, TABASCO® Sauce, and black pepper. Reduce the heat to medium-low and cook, covered, stirring occasionally for 30 minutes.
Add the yellow onion, bell pepper, celery, and garlic; cover and cook, stirring occasionally, until the mixture thickens, about 1 hour.
Add the parsley, green onions, and ground livers. Cook, stirring occasionally, until all the pink in the liver disappears, about 10 minutes. Add the cooked rice and stir to blend well; heat through and serve warm.
Makes 8 to 10 servings.
