  • 340g bag baby spinach, roughly chopped
  • 400g can chopped tomatoes with garlic and herbs
  • 225g sustainable white fish fillets, chopped into large chunks
  • small bunch basil, shredded
  • 100g cooked and peeled prawns
  • 2 tbsp finely grated parmesan
  • 2 tbsp breadcrumbs
  • 2 tbsp oats
  • 170g broccoli, boiled or steamed, to serve


  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.
