Heat the extra virgin olive oil in a paella pan or wide, shallow skillet over medium heat.
Add the diced onion and red bell pepper, sautéing for 4-5 minutes until the vegetables are softened and fragrant.
Stir in the minced garlic, smoked paprika, sea salt, and black pepper, cooking for 1 minute to release the oils.
Add the tomato puree and dry Bomba rice to the pan, stirring for 2 minutes to lightly toast the rice and coat it in the aromatics.
Pour in the seafood broth and sprinkle the saffron threads over the top; bring the mixture to a gentle boil.
Reduce the heat to a simmer and arrange the shrimp, mussels, and calamari rings evenly across the surface of the rice.
Cook undisturbed for 15-18 minutes, or until the rice is tender and the liquid has been fully absorbed.
Remove from heat, cover with a clean kitchen towel for 5 minutes, then garnish with fresh parsley and a lemon wedge before serving.
