Creating the French-Style Potato and Green Bean Salad is easy if you follow these steps:

1. Prepare the Potatoes: Wash and scrub the potatoes thoroughly. Cut them into halves or quarters if they are larger.
2. Boil Water: In a large pot, bring salted water to a boil.
3. Cook the Potatoes: Add the potatoes to the boiling water and cook for about 10-12 minutes, or until fork-tender.
4. Add Green Beans: While the potatoes are cooking, prepare the green beans by trimming the ends. When the potatoes are almost done, add the green beans to the pot and let them boil for another 3-4 minutes until tender yet crisp.
5. Drain and Cool: Once cooked, drain the potatoes and green beans in a colander and allow them to cool slightly.
6. Make the Dressing: In a small bowl, whisk together the olive oil, red wine vinegar, Dijon mustard, and minced garlic. Season with salt and pepper to taste.
7. Combine Ingredients: In a large bowl, combine the warm potatoes and green beans. Pour the dressing over the top and gently toss to coat.
8. Garnish: Sprinkle the chopped parsley on top for an extra layer of flavor and freshness.
9. Taste and Adjust: Taste the salad and adjust the seasoning if necessary by adding more salt, pepper, or dressing as desired.
