For the grilling method: Preheat grill to 400 degrees Wash your potatoes, then pat them dry. Place potatoes in a large bowl, then drizzle them with olive oil, garlic powder and salt and pepper. Place potatoes onto a large piece of foil, then add another large piece of foil on top. Seal the edges by folding a piece of foil together. Use a fork or knife to poke a hole at the top of the foil to allow some steam to escape. Place over direct heat on the preheated grill and grill for approximately 20-25 minutes or until potatoes are fork tender. This will vary depending on how large your fingerling potatoes are. Serve immediately.
