Pre-heat the oven to 180 fan. Chuck all the veggies onto a roasting tray with the olive oil and plenty of salt and pepper. Toss together and roast for 35-40 minutes or until charred and tender.
Meanwhile, make the dressing by blitzing all the ingredients in a blender together with 4 tbsp of water and a good pinch of salt until smooth.
Pour 150g of the dressing over the chicken and mix well. Cover and leave to marinade for 1 hour or overnight.
Cook the moghrabieh or orzo until al dente, drain and refresh under cold water. Drain again well and chuck into a mixing bowl. Add the remaining dressing and roasted veggies and mix well.
Preheat the grill to high and chuck the chicken onto a grill rack. Grill for 3-4 minutes a side or until charred and tender. Slice up and season with a little salt ready to serve.
