I do pretty much the same thing as I do for my delicious tuna noodle casserole, I just bake and flake some cod fillets instead of using canned tuna and I use mixed vegetables instead of peas.
It is delicious, and a great way for a non-fish lover to like fish.
Bake 4 cod filets, cool slightly, place in a large bowl and flake with a fork.
Boil a package (or two, if you want a lot) of the nice thick egg noodles that come from the frozen food section. To the flaked cod fish, add a can (or two) of cream of mushroom soup, a can of chicken noodle soup, about 2 cups of thawed, frozen mixed veggies, a handful of cheddar or mozzarella cheese, a big dollup of sour cream, a dollup of mayonnaise, a shake of Johnny's seasoned salt, a tbs of dried minced onions and a small can of evaporated milk.
Turn mixture out into a 9x11 baking pan and top with shredded cheddar cheese, dried bread crumbs and French's Fried onions. Bake at 350 degrees til heated through and cheese is melted, about 30-40 minutes.
You can also use this same recipe with canned tuna, canned chicken or canned salmon. (Or fresh.)
