Preheat the oven to 200˚C/gas mark 6.
Place the squash in a roasting tin, drizzle over the sunflower oil, sprinkle over the herbs and season well. Roast in the oven for 1 hour or until completely soft. Turn the oven off but leave the squash in the oven until needed.
Soak the couscous in an equal volume of freshly boiled water, cover and allow to stand for 10 minutes to absorb the liquid before fluffing with a fork.
Defrost the peas by covering them with freshly boiled water, leave for 5 minutes and then drain.
Remove the roasted squash from the oven and stir through the couscous, peas, almonds and extra virgin olive oil. Season to taste and serve warm.
