My mom made this tuna casserole through the years...a delicious family dish, but good for any occasion. I often serve it for a luncheon along with garlic bread and a salad. It's quick and easy to prepare, freezes well and makes a complete meal.
Tuna Mushroom Casserole is a rich-tasting main dish. The recipe was sent by Connie Moore of Medway,Ohio, who relates, "I usually serve this casserole when I'm short on time and we need something hearty and comforting."
