Fish: Each fish fillet drizzle with lemon juice and sprinkle with Vegeta Delight stock, then toss fish lightly in flour; shake off any excess.

Couscous: Prepare liquid stock: bring water to boil and add Vegeta Delight stock, cumin, saffron, margarine spread and let cook for 2-3 minutes.
Place couscous in a deeper bowl and pour it over with hot liquid stock, stir through, cover and let stand 5-10 minutes.
Vegetables: In boiling water cook broccoli florets and carrots until they start to soften, then drain and place in a serving bowl. Pour melted margarine spread and sprinkle mint and pistachio nuts over vegetables.
Stir the couscous through and serve with fish fillets and vegetables.
