Instructions

1. Fill a medium-sized bowl with water and ice for the green beans after they’ve blanched.
2. Bring a large pot of water to a boil. Add the green beans and boil them for 1-2 minutes, scoop them out with a slotted spoon, and place them in the bowl with the water and ice to stop the cooking process. Once they’ve cooled drain them in a colander.
3. Add the potatoes to the same pot of boiling water. Boil them for 15-20 minutes, or until they are fork tender. Drain them and let them cool for a few minutes.
4. While the potatoes are cooling, combine vinegar, mustard, garlic, and salt in a bowl. Whisking continuously, slowly add the olive oil until the dressing has thickened and is emulsified.
5. Once the potatoes are cool enough to handle, slice them in half lengthwise. Toss them all in a large bowl with the green beans. Add the dressing and toss it all together until everything is well coated. Add the chopped chives and black pepper, toss again, and serve.
