Prep your little potatoes (boil them for about 15 min or until they're cooked), steam the beans or boil them until they're tender-crisp (I steamed them for 2 minutes in the microwave-friendly bag they came in), and hard boil your eggs (I did an 8 minute boil). You can do this all at once if you're coordinated. ;)
Meanwhile, add all the dressing ingredients to a jar and shake to combine.
Allow your potatoes to cool for at least 15 minutes.
Assemble the salad and gently toss with the dressing. Add extra salt & pepper if desired.
