While the pumpkin and chickpeas are cooking, prepare your couscous according to packet instructions. (Normally add the same amount of water as couscous to a pan, along with a dash of oil, and heat the water to boiling. Turn off the heat and add the couscous. Stir, put the lid on and leave for 3 mins. Fluff up with a fork and allow to cool to room temperature) Note: If you want to buy pre-cooked couscous instead, that will work just as well.
