One-pan Spanish fish stew

Serves 4.

Description:
A really tasty fish and prawn stew with potatoes all cooked in one pot on top of the cooker. Everyone here had seconds.

NB. I used cod in my recipe and extra garlic. I also did not include the chick peas as I didn't realise we had run out until it was too late. we had freshly baked rolls to mop up all the juices.

Ingredients:
handful flat-leaf parsley leaves, chopped
2 garlic cloves , finely chopped
zest and juice 1 lemon
3 tbsp olive oil , plus extra to serve
1 medium onion , finely sliced
500g floury potatoes , cut into small chunks, no larger than 2cm cubes
1 tsp paprika
pinch cayenne pepper
400g can chopped tomatoes
1 fish stock cube
200g raw peeled king prawns
½ a 410g can chickpeas , rinsed and drained
500g skinless fish fillets, cut into very large chunks

Directions:
In a small bowl, mix the parsley with ½ the garlic and lemon zest, then set aside. Heat 2 tbsp oil in a large sauté pan. Throw in the onion and potatoes, cover the pan, then sweat everything for about 5 mins until the onion has softened. Add the remaining oil, garlic and spices, then cook for 2 mins more.
Pour over the lemon juice and sizzle for a moment. Add the tomatoes, ½ a can of water and crumble in the stock. Season with a little salt, then cover the pan. Simmer everything for 15-20 mins until the potatoes are just cooked. 

Stir through the prawns and chickpeas, then nestle the fish chunks into the top of the stew. Reduce the heat and recover the pan, then cook for about 8 mins, stirring very gently once or twice. When the fish is just cooked through, remove from the heat, scatter with the parsley mix, then bring the dish to the table with the bottle of olive oil for drizzling over and some crusty bread, if you want.
