Portuguese Cod Fish Casserole

"This is an easy fish meal with my mom's original ingredients," recipe submitter John J. Pacheco says. Just layer salted cod, potatoes, and onions and finish off this Mediterranean casserole with tomato sauce, olive oil, garlic, parsley, and spices.

Haddock Au Gratin

Go in a different direction with tuna casserole using this Portuguese-inspired recipe, which promises to be just as convenient to prepare. "Surprisingly good," home cook tjs775 says. "Kids ate it.
