Place couscous into a heatproof bowl, and shake to flatten.
1 cup couscous
Heat the stock until boiling (I use the microwave on high for 2 minutes), then stir butter, garlic and salt (to taste) into the hot stock.
1 cup chicken stock, 2 garlic cloves, 1 tablespoon butter, salt to taste
Pour hot stock evenly over couscous, making sure it is all covered in stock. Cover tightly with plastic wrap and leave to sit for 3 minutes.
Meanwhile, in a small frypan lightly toast the pine nuts and roughly chop the parsley (if using).
¼ cup pine nuts, ¼ cup fresh parsley leaves (loosely packed)
When the 3 minutes is up, use a fork to fluff up the couscous, then stir through grated parmesan, roughly chopped parsley, oregano leaves and pine nuts.
1 cup fresh grated parmesan, 2 tablespoon fresh oregano leaves
