Cook the quinoa according to the package directions.
Season the filets all over with the Italian seasoning, salt, and pepper.
Heat half of the olive oil in a pan over medium heat. Cook the cod for around 5 minutes on each side or until the fish is cooked through.
In a bowl, mix together the quinoa, jalapeño, capsicum and sultanas. Add the remaining olive oil and lime juice, mix well and season with salt and pepper.
Divide the fish and quinoa evenly between 2 plates. Top with a garnish of parsley and serve immediately.
