Sausage/Hash Brown/Cheddar Bake

So I just made this up on the fly as part of Easter brunch this morning - and wow, it's pretty darned good if I do say so.  And even better, really easy.  I used reduced fat sausage and cheese, so I only feel mildly guilty for having seconds.  And maybe thirds.  OK, I feel kinda guilty about that.

Sausage/Hash Brown/Cheddar Bake

1 tablespoon vegetable oil
1 pound pork sausage (I use the Jimmy Dean reduced fat kind)
1 onion, minced
1 can Campbell's cheddar cheese soup, undiluted
2 cups grated Cheddar cheese
1 pound (16 ounces, or half a package) Ore-Ida Southern Style frozen hash browns, or similar
fresh ground black pepper

Heat oven to 350F.  In a nonstick skillet heat heat oil and sauté onions until translucent.  Add sausage and cook through, using spoon to break into small pieces.  Spread sausage evenly into an 8" square glass baking dish.  Spoon soup over the meat and top with half of the cheese and a sprinkle of pepper.  Spread frozen hash browns on top; cover with the other half of the cheese and more pepper.  Bake 1 hour, and then put under the broiler for a few minutes to brown and crisp up the top.
