Preheat your oven to 400 degrees f.
Place potatoes on a roasting pan and sprinkle with garlic powder, onion powder, sea salt, and pepper to taste, and your oil. Combine really well to get the potatoes coated with everything.
Roast, uncovered, for about 30 minutes or until very tender and golden brown and crisp.
Allow to cool, then place in a large bowl.
Add in the radishes, parsley, and chives.
Just before serving, toss with vinegar and
enjoy!
