  • 1 garlic clove , sliced
  • 200g pack cherry tomatoes , stems removed and halved if large
  • 1 tbsp tomato purée
  • 300g skinless boneless white fish fillets, cut into chunks
  • 100ml vegetable stock or white wine
  • 100g cooked prawns
  • 2 sprigs tarragon , chopped
  • 750g potatoes , peeled and quartered
  • 2 spring onions , chopped

Instruction

  • Heat 1 tbsp olive oil in a non-stick frying pan and tip in the celery and garlic. Cook over a high heat for 2 mins or until softened, then add in the tomatoes. Cook for another 3 mins until starting to burst. Stir in the tomato purée and fish, then pour over the stock or wine. Turn down the heat, simmer for 3 mins, then tip in the prawns and cook for a further 2 mins until the prawns are heated through and the fish flakes easily. Stir through the tarragon and spoon the mixture into a medium-sized oval pie dish.
  • Meanwhile, cook the potatoes in salted boiling water for 15 mins until softened. Drain and mash together with the remaining olive oil, 3 tbsp water and the spring onions. Spoon over the fish mixture and smooth all over to cover. Run a fork over the surface to create swirls, then cook under a hot grill for 10 mins until the topping is lightly browned.
