1 To make the mash, place potato in a saucepan of cold water, bring to the boil and cook for 20 minutes or until tender. Drain and return to pan. Add the garlic, oil and salt and mash until smooth.
2 Combine parsley, mustard, garlic, rosemary, oil, vinegar, salt and pepper. Add chicken and toss to coat. Set aside for 15 minutes.
