1. Cut the potatoes in halves and place in a large pot. Cover with cold water and add salt. Boil over medium heat till fork tender, about 15 to 20 minutes. Do not overcook, you don’t want them to fall apart and be too mushy for the salad.
4. In a small bowl, combine the onion, garlic, beef stock, vinegar, mustard, sugar, salt and pepper, and olive oil. 5. Pour the dressing over the warm potatoes and sprinkle with parsley. Gently toss to combine.
