I have only ever eaten couscous as a salad add on. For preparation I add oil, garlic powder, soy sauce, and then cover with boiling water. I then add this to my salad, or fill a bowl with couscous and add diced tomatoes and cucumber.
But I wonder how others eat and prepare their couscous.
I used to keep a box of couscous at work for quick snacks. Little bit in a mug with a pinch of veggie stock, very tasty.
