5. Add Seafood:
– Arrange the mussels, shrimp, and calamari rings on top of the rice. Sprinkle in the frozen peas.
– Cover the pan again and cook for another 7-10 minutes, or until the mussels have opened and the shrimp are pink and cooked through.

6. Finish and Garnish:
– Season with salt and pepper to taste. Remove the pan from heat and let it rest, covered, for a few minutes.
– Garnish with fresh parsley and lemon wedges.

7. Serve:
– Serve the paella hot, making sure to give each portion a mix of seafood and rice. Squeeze fresh lemon juice over the top for added zest.

Enjoy!
