Potatoes O'Brien Casserole

This recipe has probably been the most requested of all of the brunch recipes.  My mom held a flight attendant brunch every Christmas.  I will try to scan some photos.  These potatoes are easy and delicious.  I'm not sure where the original recipe came from.  This was handwritten from what my mom verbally told me over the phone.
