In a large pot of salted boiling water, add chopped potatoes and simmer until just knife-tender, about 5-7 minutes. Make sure you don't over boil them, or they will get mushy and fall apart. We want them to be still quite firm for this salad.
Drain very well, sprinkle with a tiny pinch of sea salt, and set in the refrigerator to allow potatoes to cool a bit.
In a large bowl, combine the yogurt, olive oil, apple cider vinegar, dill, mint, garlic and onion powder.
Stir/whisk well, then add in the potatoes. Very gently stir to coat. Taste test, and adjust seasonings if you like.
Sprinkle with crumbled bacon, any extra fresh herbs, and fresh ground black pepper.
Serve immediately, or refrigerate up to 24 hours before serving.
