Step 1

Pound fresh oregano, garlic, lemon rind and 1 tsp sea salt in a mortar and pestle to a coarse paste, stir in lemon juice, oil and dried herbs, add pepper to taste and transfer to a non-reactive container. Add chicken, turn to coat, cover and refrigerate to marinate (2 hours).

Step 2

Meanwhile, for tzatziki, combine all ingredients except cucumber in a bowl, season to taste and stir to combine. Squeeze cucumber to remove excess liquid then add to yoghurt mixture, season to taste and refrigerate for flavours to develop (1 hour).

Step 3

Heat a barbecue (or char-grill pan) to medium-high heat. Drain chicken from marinade and char-grill, turning occasionally, until cooked through (8-10 minutes). Season to taste and thickly slice.

Step 4

Top warm pita bread with chicken, tzatziki and salad and serve with lemon wedges.
