NOTE: Use as much spinach as you can pack into your baking dish because spinach does shrink quite a bit.

1. First, pack spinach onto the bottom of a baking dish. Top with butter slices and layer the fish fillets over the top

    Super easy and completely delicious! I was able to substitute plain yogurt for some of the sour cream and mayonnaise and it still tastes great but with less fat/calories. Good enough to serve to company and get rave reviews, which we have done!

      That’s wonderful to hear, Betsy! Thanks for the low calorie tip!

    Please give the nutritional information for a 1 oz serving. Currently you show it for serving size of 1g which isn’t very much — maybe a tablespoon? Thanks
