8 to 10 lg. russet potatoes
1 can cream of mushroom soup, undiluted
1 (12 oz.) pkg. Colby cheese, shredded
1 lg. onion, chopped fine
Salt and pepper to taste

Spray 9x13 inch glass pan with Pam. Slice potatoes thinly, peeling if you want to. Place in large bowl and add rest of ingredients and squish together until well mixed. Use plenty of salt. If potatoes look too dry, add more soup.

When mixed well, spread into sprayed pan and bake, covered, at 375 degrees for 30 to 40 minutes or until tender. Last few minutes you can remove foil and top with crumbled corn flakes and let brown. Really good.
