Preheat grill to medium heat. Mix butter and garlic powder together. Slice potatoes lengthwise in 1/4 inch slices. Coat potato slices with butter mixture and place on grill. Grill each side for 3-4 minutes, watching carefully. Remove from the grill when potatoes are tender. Sprinkle with seasoned salt immediately after removing from the grill. Serve with sour cream and ketchup, if desired. |
