Add the giant couscous and stock to a saucepan and simmer over a medium heat for 6 minutes. When cooked, the couscous will have doubled in size and absorbed the water. Don’t overcook it as it will become gluey and stick together.
Set the cooked couscous aside to cool.
Mix the cooled couscous and the rest of the ingredients together.
Season with salt and pepper to taste and serve.
