In the paella pan, heat olive oil over medium heat. Add chopped onion and minced garlic, sauté for a few minutes until fragrant.
Add diced bell peppers and frozen peas to the pan. Cook for 5 minutes until the vegetables have softened.
Push the vegetables to one side of the pan and add the sliced chorizo. Cook until browned, then mix with the veggies.
On the other side of the pan, add the shrimp and mussels. Sauté for 2 minutes until the shrimp starts to turn pink.
Move the seafood to the center of the pan and add the rice on top. Stir to coat the rice in the oil and juices.
Pour in the chicken broth and sprinkle saffron threads and smoked paprika over the top. Season with salt and pepper to taste.
Let the paella cook for 30-35 minutes, stirring occasionally, until the rice is fully cooked and the liquid is absorbed.
Remove from heat and let it rest for 5 minutes.
Serve hot with lemon wedges and freshly chopped parsley on top.
Notes
For a vegetarian option, omit the seafood and substitute vegetable broth for the chicken broth.You can also add other seafood such as clams, scallops, or calamari to the paella.To make it spicier, add some diced jalapenos or red pepper flakes.Saffron can be expensive, but it adds a unique flavor. If you don't have saffron, you can substitute with turmeric.This dish is best served immediately, as the rice can become mushy if left to sit too long.
