In a bowl, mix together the yogurt, half a tablespoon of oil, the garlic and herbs. Add the chicken fillets, cover and leave to marinate for a couple of hours or overnight. Preheat the grill.

Meanwhile, boil the potatoes until tender, drain, smash roughly with a fork and stir in the remaining olive oil and the zest. Season to taste and garnish with some parsley leaves. Serve the chicken with the potatoes and some salad.
