Sauté Vegetables: In a large pan or paella pan, heat olive oil over medium heat. Add the diced onion, minced garlic, and chopped bell pepper. Sauté for 4-5 minutes until softened.

Prepare Rice: Stir in the rice, smoked paprika, and saffron (with its soaking liquid). Add the crushed tomatoes and seafood broth, bringing the mixture to a simmer.

Cook the Fish: Add the chunks of firm white fish to the pan. Let it simmer for 10 minutes, allowing the rice to absorb the liquid and the fish to cook through.

Add Seafood: Add the shrimp, mussels, clams, and peas. Cover the pan and cook for another 5-7 minutes, or until the shellfish have opened and the shrimp is cooked through.

Garnish and Serve: Garnish the paella with freshly chopped parsley and serve with lemon wedges on the side for an added burst of flavor.
