In a small bowl, whisk dressing ingredients together & set aside.
Place potatoes in a medium pot filled with cold, salted water. Bring to a boil, then lower heat & boil gently, just until potatoes are fork-tender, about 8-12 minutes. Drain & rinse in cold water to stop cooking.
Place potatoes in a large bowl & toss with a generous amount of the dressing (save some for later use). Add green onions, chopped pickles & dill; toss gently. Top with sliced eggs; Refrigerate for at least an hour or two to let the flavors mingle. Add more dressing, if necessary. Garnish with extra dill & chopped pickles, if desired.
