Heat the extra virgin olive oil in a paella pan or wide skillet over medium heat.
Add the diced Spanish chorizo and cook for 2-3 minutes until the oils are released and the edges are crisp.
Stir in the diced yellow onion and red bell pepper, sautéing until the vegetables have softened, about 4 minutes.
Add the minced garlic, smoked paprika, and Bomba rice, stirring constantly for 1 minute to toast the rice grains.
Pour in the tomato puree and chicken broth, then crumble the saffron threads into the liquid; season with sea salt and black pepper.
Bring the mixture to a boil, then reduce the heat to low and simmer undisturbed for 10 minutes to allow the rice to absorb the liquid.
Arrange the shrimp and scrubbed mussels on top of the rice, pressing them down slightly into the liquid.
Cover the pan with a tight-fitting lid or foil and cook for another 8-10 minutes until the rice is tender, the shrimp are opaque, and the mussels have opened.
Remove from heat, garnish with freshly chopped parsley, and serve immediately with a lemon wedge.
