Heat the extra virgin olive oil in a wide, shallow skillet or paella pan over medium heat.
Add the sliced Spanish chorizo and sauté for 2 minutes until the smoky oils are released.
Stir in the diced yellow onion and red bell pepper, cooking until softened, about 4 minutes.
Add the minced garlic, smoked paprika, sea salt, and black pepper, stirring for 30 seconds until fragrant.
Pour in the tomato puree and the dry Bomba rice, stirring to ensure every grain is coated in the oil and spices.
Add the saffron threads to the seafood stock and pour the liquid into the pan; bring to a gentle simmer.
Reduce the heat to low and cook undisturbed for 10-12 minutes to allow the rice to absorb the liquid.
Nestle the shrimp and cubed cod fillet into the rice, then cover the pan with a lid or foil.
Cook for an additional 5-7 minutes until the shrimp is pink and the fish is opaque and flaky.
Remove from heat and let rest for 2 minutes before garnishing with fresh parsley and serving with a lemon wedge.
