Ham Potato Scallop

1 pkg (5 oz) scalloped potatoes
2 cups boiling water
2 tbsp butter or margarine
3/4 cup milk
2 cups fully cooked ham
1 pkg (10 oz) frozen cut green beans
1 cup (4 oz) shredded cheddar cheese

In a 3 qt ungreased casserole dish, combine potatoes w/ sauce mix, boiling water and butter. Stir in milk, ham and green beans. Bake uncovered around 35 mins at 400 or until the potatoes are tender, stirring occasionally so that the potatoes don't brown. Sprinkle w/ cheese and bake 5 more mins until cheese is melted. Let stand about 5 mins before serving.
Yields 4-6 servings.
