Creating Green Bean Potato Salad is easy when you break it down into simple steps. Follow these instructions for a delicious and nutritious dish:

1. Cook the Potatoes: Place the cubed potatoes in a large pot of boiling salted water. Cook for about 10-12 minutes or until the potatoes are fork-tender. Drain and set aside to cool.
2. Blanch the Green Beans: In the same pot of boiling water, add the green beans and blanch for about 3-4 minutes until bright green and crisp. Drain and place in ice water to stop cooking. Once cooled, drain again.
3. Prepare the Dressing: In a small bowl, whisk together the mayonnaise, apple cider vinegar, Dijon mustard, salt, and pepper until smooth. Adjust seasoning to taste.
4. Combine Ingredients: In a large mixing bowl, combine the cooled potatoes, green beans, red onion, and cherry tomatoes. Pour the dressing over the salad and gently toss to coat all ingredients evenly.
5. Chill: For the best flavor, cover the salad and refrigerate for at least 30 minutes before serving.
6. Serve: Before serving, garnish with freshly chopped herbs if desired.

These straightforward steps will lead you to create a Green Bean Potato Salad that is utterly delicious!
