olive oil mash
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.
Combine parsley, mustard, garlic, rosemary, oil, vinegar, salt and pepper. Add chicken and toss to coat. Set aside for 15 minutes.
Heat a large non-stick frying pan over medium heat. Cook the chicken for 6–8 minutes on each side or until cooked through. Spoon over the pan juices and serve with the mash.
