Heat a large fry pan with a medium heat and add in the olive oil

In the meantime, add the cod fillets over some paper towels and pat dry, then season them with sea salt & black pepper on both sides and cut each fillet into 2 evenly sized pieces for a total of 6 pieces of fish

Add the pieces of fish into the hot fry pan, all in a single layer and evenly spaced out, cook for 2 minutes per side, then remove from the pan and cover with foil paper (at this point you don't have to fully cook the fish through)

Using the same pan with the same heat, add in the chopped onion and garlic, mix continuously, after 5 minutes and the onion is translucent, add in the rice, saffron, rosemary, thyme, and season generously with sea salt and black pepper, mix continuously for 2 minutes, then add in the water and raise to a high heat, give it a gentle mix

When it comes to a boil, place a lid over the pan and lower to a low heat

Once the rice is 3 minutes shy of being cooked through (check rice package instructions) remove the lid, add in the frozen peas, using a fork gently fluff the rice, then add the pieces of fish back into the pan, once again in a single layer, place the lid back on the pan and simmer for another 3 minutes or until the rice and fish are cooked through, then remove from the heat

Squeeze the lemon juice over the fish and rice and garnish with chopped parsley, enjoy!
