Heat the extra virgin olive oil in a paella pan or wide shallow skillet over medium heat.
Add the diced Spanish chorizo and sauté until the fat renders and the edges are slightly crisp.
Stir in the diced yellow onion and red bell pepper, cooking until the vegetables are softened and fragrant.
Add the minced garlic, smoked paprika, and tomato puree, stirring constantly for 2 minutes to develop the base flavors.
Pour in the Bomba rice and stir to ensure every grain is well-coated with the aromatic oils and tomato mixture.
Crumble the saffron threads into the seafood broth and pour the liquid into the pan, adding sea salt and black pepper.
Bring the liquid to a gentle simmer, then reduce the heat to low and cook undisturbed for 15 minutes.
Carefully nestle the shrimp and mussels into the rice, then cover the pan with a lid or foil for 5 to 7 minutes.
Remove from heat once the shrimp are pink and opaque and the mussels have opened completely.
Garnish with freshly chopped parsley and serve with a lemon wedge to brighten the flavors.
