Heat the olive oil in a wide skillet or paella pan over medium heat.
Add the sliced chorizo and cook for 2 minutes until the fat renders and the edges are crisp.
Stir in the diced onion and bell pepper, sautéing until the vegetables are softened and fragrant.
Add the minced garlic, smoked paprika, sea salt, and black pepper, stirring for 30 seconds to toast the spices.
Pour in the tomato puree and Bomba rice, stirring for 1 minute to coat every grain in the flavorful oil.
Mix the saffron threads into the seafood broth and pour the liquid into the pan.
Bring the mixture to a boil, then reduce the heat to a gentle simmer; do not stir the rice again to ensure a crust forms.
Arrange the shrimp and mussels on top of the rice, pressing them down slightly into the liquid.
Cook uncovered for 10-12 minutes until the broth is absorbed and the mussels have opened wide.
Scatter the peas over the top, cover the pan, and let it rest off the heat for 5 minutes to finish steaming.
Garnish with chopped fresh parsley and serve with lemon wedges for a bright finish.
