Preheat the oven to 200 degrees C (390 Fahrenheit).
Cut the butternut squash in half lengthwise.
Scoop out the seeds and place the two halves on a baking tray.
Bake for an hour until the flesh is soft.
Heat up the oil in a pan and add the onion chopped finely.
Fry for 2-3 minutes until it softens, then add the chopped courgette and red pepper, give them a good stir, add the vegetable stock and boil for 15 minutes.
Use a spoon to scoop out the flesh from the butternut squash, leaving about 1 ½ cm around the edges.
You can add some of the flesh to the pan. I enjoyed the rest of it on its own, it’s super delicious!
Take the pan off the heat, add the couscous and place a lid on the pan.
After 5 minutes, remove the lip the fluff the couscous up with a fork.
Season with salt and pepper and mix in the tomato purée.
Stuff the butternut squash halves with the couscous, sprinkle some grated cheese over, and bake in the oven for a further 5-10 minutes.
Garnish with freshly chopped parsley.
