Place the cut potatoes in a large pot. Cover with water by at least 2 inches and salt the water well. Bring the water to a boil and boil the potatoes uncovered for 7-10 minutes just until fork-tender but not mushy. Drain the potatoes and place them in a bowl to cool.
While the potatoes are boiling, I chop, slice, and measure the rest of the ingredients.
When the potatoes have cooled just slightly but are still warm, drizzle with the oil and vinegar. Add the salt and a few grinds or pinches of black pepper, and stir gently to combine.
Taste the potatoes for seasoning. They should taste wonderful. If they’re a little bland or dry, add more salt, pepper, oil, or vinegar until you think “wow, that’s a really freaking good plain potato.” Salt is usually the answer here.
Add the herbs and scallions to the potatoes. Stir gently again, and taste once more to be sure the potato salad is amazing.
Serve warm, at room temperature, or cold. Enjoy!
