Famous Green Bean Casserole

This is the old favorite recipe, revised to a lower fat, lower sodium recipe. It is quite good.

2 (9 ounce) bags frozen green beans, thawed, or
    2 (15 ounce) cans no salt added green beans, drained
1 (10 3/4 ounce) can Campbell's HEALTHY REQUEST
    Cream of Mushroom Soup
3/4 cup skim milk
1 (3.5 ounce) can Real Bak'd Onion Pieces, divided
1/8 teaspoon ground black pepper
2 teaspoons Worcestershire sauce or soy sauce (optional -
    note these are high sodium products)

In a 1 1/2-quart casserole, mix all ingredients except 1/2 can of the Real Bak'd Onion Pieces.

Bake uncovered 30 minutes at 350 degrees F or until hot; stir. Top with remaining 1/2 can of Real Bak'd Onion Pieces. Bake an additional 5 minutes.
