Bring a large pot of water to a boil and add potatoes.

Scrub potatoes clean. Slice into ½-inch thick slices and place into the boiling water and cook over medium heat for about 10 minutes. Potatoes will not be cooked all the way through.

Meanwhile, in a large, shallow dish/pan, whisk together olive oil, parsley, garlic powder, salt and pepper. Pour the olive oil mixture into a shallow dish.

Drain the potatoes well, patting them dry if necessary, and toss them in the olive oil mixture.

Preheat an outdoor grill to medium heat (350-375 degrees F).

Shake excess oil off of each potato slice and place onto the grill 2-3 minutes per side. Transfer potatoes to a plate and tent with foil until ready to serve.

Garnish with fresh parsley and lemon wedges.
