Combine quinoa and water together in a saucepan. Bring to a boil and then reduce heat to a simmer and cover with a lid. Let simmer for 13 to 15 minutes or until water is absorbed. Remove lid and fluff the quinoa with a fork. Turn off the heat and set aside.
Meanwhile, add the trout and bok choy to a baking sheet and gently coat in oil. Season with salt and sesame seeds. Bake for 10 minutes or until the fish is cooked through.
Divide the quinoa, trout and bok choy onto plates. Enjoy!
