  1. Put the spinach in a large colander and pour over boiling water. Once cool enough to handle, squeeze out any excess water, then season.

  2. Tip the tomatoes into a frying pan with some seasoning and simmer for 5 mins to thicken. Add the fish and heat for 1-2 mins – it doesn’t need to be fully cooked at this point. Stir in the basil.

  3. Heat oven to 220C/200C fan/gas 7. Divide the spinach, fish, prawns and tomato sauce between 2 gratin dishes. Mix the Parmesan, breadcrumbs and oats together and sprinkle over the top. Bake for 20 mins until golden and bubbling. Serve with cooked broccoli.

Not a fan of this recipe. Followed some of the tips from previous reviews and added onion lightly fried, more garlic and some chilli flakes. Still found it a really bland dish - wouldn’t make again.

Quick and easy. Would probably add Chilli next time

Delicious, definitely making this again! I recommend a good quality tomato base such as Loyd Grossmans jar of tomato and roasted garlic, yum!

Am not sure how this manages to hit all 5 of the fruit & veg portions in one go, but was an ok supper dish. Didn't blow me away, but was nice enough!

This looked so different I wanted to love it but for us it fell short of something.Wasn't keen on the textures so we just picked out the fish really.Added scallops otherwise stuck to recipe.Wish I had added mushrooms as suggested above.

Marilyn, I do health inspections based on the US FDA Food Code. We recommend cooking seafood to at least 145 degrees F (not sure in Celsius). Grab a properly calibrated food thermometer and you will have no worries. I thought the dish was delicious, moist and not too acidic. Used tilapia as the fish and added sautéed onions, cilantro, and portobellos. Didn't have broccoli. Seasoned with Lawry's seasoned salt.
