Fast one-pan fish

This is a great supper dish- very quick and easy. It's from Prima magazine.
Serves 4
Ingredients
1 tbsp olive oil
2 courgettes
2 cloves garlic, finely chopped
2 tsp paprika
1 red pepper, halved, de seeded and cut into strips
6 fresh tomatoes, chopped
Handful of mixed black and green olives, pitted, large ones halved
3 preserved lemons, halved and flesh removed (or use zest of 1 lemon)
4 cod or haddock fillets (150g each)

1. Heat the oil in a large frying pan, add courgettes and garlic and season. Cook for 1 min until pale golden, sprinkle in paprika and serve.
2. Add pepper, tomatoes, olives and lemons. Bring to the boil and simmer with a lid on pan for 10 mins. Top up with a little hot water, if needed.
3. Add fish, cover and cook for 1 min. Remove from heat and leave lid on for 3-4 mins- fish will continue to cook until ready to serve. Season again if needed.
