Cheesy Scalloped Potatoes

1/2  cup  butter, melted

1  med  onion, chopped

1  can  cream of mushroom soup, undiluted

12  oz  Cheez Whiz

1  can  mild green chilies

Chopped green onions

1/2  cup  butter, melted

3  cups  corn flakes

Combine  first 7 ingredients and put in a 9x13" Pyrex baking dish. Sprinkle with some chopped green onions. Mix the remaining 1/2 cup melted butter with the corn flakes. Sprinkle over the top.
