My mother in law made this. I got it from her. I change mine around deleting some ingredients and adding more of others. Play with it to your liking. You can substitute canned chicken for the tuna. I also use the bagged Homestyle wide noodles We love it served with garlic bread. You can make this ahead, keep refrigerated and cook later. You may have to adjust the cooking time and wait to put the cheese on top until almost done cooking.
