Ready, Set, Cook! Special Edition Contest Entry: Try this yummy cheesy zesty potato casserole! It has all of the southwest flavors I love. It's very comforting and satisfying too. It is super easy to throw together, and uses pantry staples most of us have on hand. I really enjoyed it with tuna, but I think it would be just as good Vegetarian or with cooked chicken, cooked ground beef or cooked sausage. I made this pretty mild, but it can easily be spiced up with fresh or canned jalapenos or added red pepper flakes or hot sauce. Feel free to use reduced-fat cheese.
