Heat sesame seed oil in a pan over medium high until shimmering. Add monkfish cook for about 10-15 mins or until cooked through. You will need to cook on all four sides, 3-5mins on each side. When done, remove from pan and set aside, covered.
Clean the mushrooms, leek, parsley and chop very finely. Peel the garlic and chop. In the same pan as the fish was cooked, heat 1 tbsp sesame oil, add garlic and sauté. After 2 minutes add the leek and cook for 2 minutes, stirring occasionally.
Then add mushrooms and chopped herbs, reduce the heat and stew until the mushrooms let water. Add the soy sauce, salt, ginger powder and sesame seeds and let simmer for 2-3 minutes.
While this is cooking, cook couscous in a separate pot to instructions. When done, add couscous to the mushroom mix. Remove the pan from the heat and Stir everything well.
Preheat the oven to 400.
I made this for dinner last night and it was a huge hit.
