Heat olive oil in a paella pan over medium heat. Add chicken and chorizo, cook until browned. Remove and set aside.
Add onions, bell peppers, and garlic to the pan. Sauté until softened, about 5 minutes.
Stir in tomato paste and smoked paprika. Cook for 1 minute more.
Add the rice and saffron. Stir to coat the rice with the mixture.
Pour in the chicken broth. Bring to a boil, then reduce heat and simmer for 15 minutes, without stirring.
Arrange shrimp, mussels, and clams over the rice. Add the cooked chicken and chorizo back to the pan. Cover and cook for another 10-15 minutes, or until the seafood is cooked and the rice is tender.
Let the paella rest for 5 minutes before serving. Garnish with lemon wedges and parsley.
I struggled with the socarrat. It didn't get crispy at all, and the bottom layer of rice was mushy. The flavors were okay, but the texture was off. Perhaps I needed more heat.
