Heat the extra virgin olive oil in a paella pan or wide skillet over medium heat.
Add the diced onion and red bell pepper, sautéing until the vegetables are softened and fragrant.
Stir in the minced garlic, smoked paprika, and saffron threads, cooking for one minute to release the aromatics.
Add the tomato puree and cook for another two minutes to create a thick base.
Stir in the Bomba rice, ensuring every grain is well-coated with the tomato and spice mixture.
Pour in the seafood broth and season with sea salt and black pepper.
Bring the liquid to a gentle simmer and cook undisturbed for 10 minutes to allow the rice to begin absorbing the broth.
Arrange the shrimp and scrubbed mussels on top of the rice, pressing them down slightly into the liquid.
Cover the pan and continue to cook for 5 to 8 minutes until the shrimp are pink and the mussels have opened.
Remove from heat, garnish with fresh parsley, and serve with a lemon wedge for a bright finish.
