Cheesy Brat Casserole

Ingredients Directions
 * 6 fully cooked Polish or sweet italian sausage or bratwurst, cut into 1/2-inch pieces or chunks of various sizes
 * 4 medium potatoes, cooked, peeled, and cubed (1 1/4 pounds)
 * 16 ounces frozen cut green beans, thawed and drained
 * 10.75 ounce can cream of mushroom soup
 * 1 cup shredded cheddar cheese (how do you measure a "cup" of cheese?  I just use a lot of cheese)
 * Additional parmesean cheese to taste
 * ⅓ cup chopped onion (I like it sliced thin and long)

Cook up sausages in a large-ish frying pan, reserving any grease (I tend to cook them whole, then slice them up after they're cooked). Remove snausages and add potatoes, and maybe a little bit of butter or oil, to fry up the potatoes

In a 3-quart casserole, stir together the sausage, potatoes, green beans, soup, cheddar cheese and onion. Sprinkle some extra cheese (cheddar and parm) on top to a crispy cheese top.

Bake in a 350° oven for about 45 minutes or until heated through.
