Overnight Tuna Casserole

Author Notes: This uncooked casserole goes in the refrigerator than is baked after turned to room temperature. It is incredibly simple, extremely easy and highly versatile. When I only have spaghetti, I just break it into small pieces and use it; I always use whole wheat pasta, because I like it so much. I like to use Cheddar Cheese plus Nacho or Cream of Onion condensed soups in this recipe. Also, you can use any kind of cheese you like. Instead of peas, you can use carrots, or a veggie combination. I sometimes double the amount of veggies. And if you like garlic, it is a great addition. Don't twist your nose and dismiss it because it has condensed soup: this is absolutely delicious. And I don't even like tuna casserole!MrsK
