Cheesy Ham and Potato Casserole

Here's one for Alex:

1 package frozen cubed hash browns
1 family-sized cream of chicken soup
1 package cubed ham, drained
1 16 oz. container sour cream
2 cups orange cheese--I use colby jack.  medium cheddar would be great
2 chopped green onions, optional

Preheat oven to 425 degrees.  Lightly spray a 9x13 pan.
In a very large bowl, combine soup and sour cream.  Add ham, 1.5 cups of the cheese, and the hash browns.  Stir all together until well combined.  (add sliced green onions if adding them).  Pour into the 9x13 pan and smooth.  Sprinkle remaining cheese over top of casserole.  Spray non-stick spray on a piece of aluminum foil that will cover the pan; place on pan sprayed-side down.  Scrunch around sides and put into oven for 30 minutes.  Check and see if it is boiling through; add time 5 minutes at a time until lightly browned and boiling through.  Serve with garlic bread and vegetable or salad.
