Heat the extra virgin olive oil in a paella pan or wide skillet over medium heat.
Add the diced Spanish chorizo and sauté for 2 minutes until the oils are released and the edges are crisp.
Stir in the finely diced onion and red bell pepper, cooking until softened, then add the minced garlic and smoked paprika for 30 seconds.
Pour in the tomato puree and cook for 2 minutes to create a thick sofrito base.
Add the Bomba rice and stir to coat every grain with the aromatic oil and tomato mixture.
Crumble the saffron threads into the seafood broth and pour it over the rice; do not stir the rice again to allow the bottom crust to form.
Simmer on medium-low for 10 minutes, then nestle the shrimp and scrubbed mussels into the rice.
Cover and cook for another 5-8 minutes until the rice is tender, the shrimp are pink, and the mussels have opened.
Season with sea salt and black pepper, then garnish with fresh chopped parsley and a lemon wedge before serving.
