Start with the orzo. Heat one tablespoon of the olive oil in a large pan over a medium heat. Peel and finely chop the onion and garlic. Add to the pan and cook for 2-3 minutes.
Grate or peel the lemon rind and add to the pan. Allow it sweat for 30 seconds, then add the orzo, chicken stock cube and 900mls water.
Bring to a simmer and cook gently for approximately ten minutes, until the orzo is al dente. Stir regularly so that it doesn’t stick.
Stir in the peas, crème fraiche and Parmesan. Cook for another minute, then turn the heat off while you cook the salmon.
Sprinkle the skin of the salmon fillets with salt. Heat the remaining tablespoon of olive oil in a separate frying pan and add the salmon (skin side down). Cook for 5 minutes skin side down, then flip and cook for 30 seconds on the other side. Remove from the pan.
Finish the orzo by stirring in the chopped parsley and lemon juice. Serve the orzo in bowls topped with a salmon fillet.
