Fall weather puts me in the mood for comfort food such as casseroles, but I don't want all the calories that usually come with them. So I paired cod with potatoes and used an Italian inspired tomato sauce to bring it all together. My partner and I really enjoyed this last night and I hope you will too. You can use any type fish you like, as long as it flakes easily when cooked. I think I'm going to try smoked salmon next time. For the potatoes, I like to use Yukon gold, but any low starch potato will work well.
