I attended a Boy Scout pot luck with my son several years ago and was introduced to these heavenly potatoes. The Scout leader was kind enough to share. It is a recipe that is hard to mess up but yet is delightful enough to serve at a formal dinner party. We seldom have leftovers and when we do my family fights over who gets to eat them. It is an easy recipe to decrease or increase depending on the needs of your family.
I don't like using Cheese Whiz in casseroles, so I wouldn't make this until my sister-in-law served it one night. No Cheese Whiz, just real cheddar cheese. Delicious, and kid-friendly.
