Place the couscous in a bowl, pour in the boiling salted water, cover and leave to absorb for approx. 10 mins. Separate the couscous with a fork. Heat the oil in a pan, sauté the spring onions (set aside the greens), add the garlic, cook briefly. Add the squash and cook for approx. 3 mins. Add the mince, pour in the bouillon or wine, bring to the boil, add the currants, reduce the heat, simmer for approx. 5 mins. Season the filling. Remove the pan from the heat, mix in the herbs and reserved onion greens.
