Stir the soup, milk, soy sauce, black pepper, beans and 2/3 cup onions in a 1 1/2-quart casserole.
Bake at 350°F for 25 minutes or until the bean mixture is hot and bubbling. Stir the bean mixture. Sprinkle with the remaining onions.
Bake for 5 minutes or until the onions are golden brown.
Flavor Variation: For Golden Green Bean Casserole, substitute Campbell's® Condensed Golden Mushroom Soup for the Cream of Mushroom Soup. Omit the soy sauce. Stir in 1/4 cup chopped red pepper with the green beans.
