I did try to find the post for Tuna Glop but couldn't find it. I will have to look at home and re-post the recipie or maybe I'll just reconstruct from memory. Ginny can add anything I miss.
It's not that hard, mostly just tuna (or chicken if you choose), one of the cream soups, like cream of musroom or celery or chicken and the main ingredient, a box of Mac and Cheese. You can use Kraft or the store brand. Prepare the mac and cheese according to directions then add the cream soup and tuna or chicken and bake at 325 for a half hour. Serve with a side dish if you choose (a vegetable or a salad) although the casserole is very filling by itself so you don't need a salad unless you're really hungry. You can also add things to the recipie. I put in green beans and mushrooms and added crushed Wheat Thins on top for extra crunchiness. When we had the leftovers yesterday I put in some leftover cous cous as well (Sunday we had salmon and cous cous and green peas).
