Heat olive oil in a large pan over medium heat.

Add onion, bell pepper, and garlic to the pan. Cook until vegetables are softened.

Stir in tomato sauce, bay leaf, paprika, salt, and pepper. Cook for 2 minutes.

Add white wine, chicken breast, sausage, parsley, shrimp, mussels, Spanish rice, and chicken broth to the pan. Bring to a boil, then reduce heat to low. Cover and simmer for 25 minutes or until rice is cooked and liquid is absorbed.

Remove bay leaf before serving. Garnish with additional parsley if desired.
