Defrost the cod fillets by placing the packet/ bag into room temp/ warm water.
Start by adding the diced onion, chopped chilli and grated ginger in a large saucepan on a low heat with a tbsp of olive oil. Gently sautee for around 6 minutes, until the onions are translucent.
Then, add the garlic and cherry tomatoes to fry for a couple, stirring frequently. After 2 minutes, add the seasoning (curry powder and turmeric) and continue to fry for a few minutes to allow the spices to bloom.
Then add the fish stock, lemon grass and cook for 5 minutes, until reduced by around half. Meanwhile, pop your rice on to cook, timer set according to the packet time. Mine was 12 minutes long.
Pour the coconut milk and spinach into the pan with the curry and stir to combine. Then gently add the defrosted cod fillets into the pan and cook over a medium heat for 8 minutes.
Serve with a sprinkle of coriander leaves and some optional chilli flakes for some added heat.
